Top,
the law should be on your side. You say they ser up a "camp". Is there actually a house ro building, or do they all live in tents. If they're in tents, I bet there;s a whole passel of laws/ordinances they're violating. Start with vagrancy laws. Then try zoning laws. If they've set up a "camp", I wonder how they're dealing with water and sewage. If they're running a generator 24/4 I bet you can get them condemned. Around here, for a domicile (home) to be legal for habitation, it has to have running potable (drinkable) water, some sort of legal (probably certified) sewage system (city or septic system), and it has to have utility-powered electricity. You can live "off the grid" with nothing but wind power, but if you're in town, ya gotta have a power meter (even if it runs backward).
There should be someone with the city that is willing to help you. There should also be somewhere that offers free legal council. Maybe not in your town, since it's so small, but somewhere close.
I would avoid taking any sort of overt action on your own. As satisfying as it might be at the moment, you don't want to be the one that goes outside the boundary of the law.
One more thing, and this is pretty important: document everything you do with regards to this problem. Write down every time you talk to these folks. Write down the activities the concern you. Write down all the phone calls and contacts you have with city management and law enforcement - get names and describe conversations. If everything else fails, go public - get the local TV stations involved. Let them ask why the city is letting things slide.
This family is the "Bane" of the town, but even the Town Clerk can't seem to do much about them.
The Law SHOULD be on my side, but that's not the way it works around here. Like I said, even when I was attacked while riding my bike by one of their Dogs back in 11', I was unable to recover damages for my medical bills due to a law here in Vermont that if someone has less than $70,000 in assets they cannot be sued, and these folks don't have any liability insurance.
Their family owns the land they are on, so they are not squatting or tresspassing. There are originally 13 adult children in the family, and they all live in trailers, shacks or campers on their property. A few of them moved to a different part of the state and set up a colony/homestead there, where I hear the conditions are equally abhorrent.
As far as water and sewage, they have a porta-potty that a truck comes and cleans once a week. They have jobs, and their property is basically all a farm, so they get by just fine, and since they are used to living like this it does'nt bother them.
Once, while walking my Dog up the road, they were shooting at an unsafe back stop, and bullets were ricocheting out into the road infront of me. I yelled out, "Hey, what they $%^&" and they realized what was going on and quickly came and removed the target from where it should not have been in the first place. I did call the State Police in that case, but their response was "What do you want us to do about it?" I told them that I guess I just wanted them to be aware and to make a note of it because if someone gets hurt, it needs to be known that these folks are pretty dumb.
Sadly, CVS Drugstores, Convenience Stores and Banks get held up almost every day here in Vermont, and the crooks seem to be onto something, because I NEVER hear of them making an arrest, so it's open season on Banks and such here.
Now, with the escapees from Clinton Correctional on the loose, who will almost certainly elude the Northeasts finest, they would have even less time to spend for a neighbor dispute.
Interestingly, the only times you hear about gun violence here in Vermont, it is typically two neighbors that feuded for years, and the police were well aware of it but did nothing.
My killing days ended when I left Iraq, and my days of being naive enough to think that there is a way to win against this family of hillbillies are over too.
It is time to leave this property. I have over the past couple of days gotten most of my important possessions moved over to my Moms basement, and have made many contacts in the Veterans community that are working to get me the help I need to get out of here, and am waiting on some more phone calls today. Staying here is not an option anymore, as even if I was able to make them leave, they would surely seek retribution which would lead to armed conflict and me ending up in prison.
The desire for revenge and thirst for retribution is what made me join the Army after 9-11, and I did my best to get it, but it is an emotion and a way of being which consumes you entirely and is extremely unhealthy. I will not be that person again for the sake of my Son and my Animals. I deserve peace, as I know I have earned it.
The only good things that has come of this if you can look at it that way is that I have tightened up a few more notches on my belt, as the anxiety has caused my appetite to fade. Also, I am making all these fixes to my house that have gone by the wayside due to the fact I did'nt NEED to make them when I was planning on staying.
I have taken the file folder that I was going to use as a flight log for rockets and converted it to be my moving log book, where I catalog a to do list and keep all of the contact info that I've made over the past couple of days.
Anyhow, It looks like at least I really have the ball rolling here, and there are even more phone calls I need to make today.
Like all things in life, a challenge can be a learning opportunity, and I will face this as such.
When I prevail, I will share my experience with other Veterans who might find themselves in similar circumstances, that they made benefit from my struggle. I have faith that this will eventually be like every other adversity I've faced, and become part of my past.
The Sheriff's here WILL help you out. They take Peace and Quite very seriously...you can trust me on that. Plus we have HUGE areas to fly in. The Tripoli chapter has their spot just off the Snake River where the road drops into the Swan Falls dam, good fishing
