All high power rockets at BattlePark must use rails, either 1010, 1515, or unistrut. We also supply several 1010 rails for Low power fights.
On the webpage under the UPDATED 2021-22 Launch Season there are links to pre-register, a paypal link to pay the dues, and a link to flight cards you can fill out and print to bring along.
You are correct, Tripoli Central Virginia #25 is not listed on the NAR site. We are Tripoli prefecture only. There are plenty of NAR member that can provide NAR L1, L2, and even L3 certification flights.
I see you bought an Estes Doorknob rocket. You can certainly try a L1 certification with the rocket, but I would highly recommend against it. That is a mid powered rocket, not a high power rocket. It is designed to fly on D, E, & F motors. If you put a BABY H motor in that you will exceed 2000 ft and may reach 3000 ft. Your chance of ever seeing it again is greatly reduced.
For L1 flights on the east coast, I recommend a rocket with 38mm MMT, 3" - 4" diameter, and 4 - 6 lbs. for a L1 cert. That will stay low and slow with a baby H motor, but allow you to fly the full range of H & I motors after your cert and not "out-fly" the field.
Look me up when you come out on the 12th. I'm the guy with the Steampunk top hat.
