Working with Carl as your L3 Cert Advisor? Oh my... I can just hear that now....
L3 Candidate: "So, any suggestions Mr. Tulanko, Mr. L3 Guru-guy?"
Carl: "Yep. It's not big enough. I think you should double the design specifications - make it a 15" diameter rocket with twin M's for power. It should weigh at least 180 pounds. Oh, and another thing - you need to start ordering West Systems epoxy in the 55 gallon drums. Not only are you going to need that much, but my Gougeon Brothers stock is not performing as well as I'd like and your purchase will help them out."
L3 Candidate: "Anything else, Mr. Tulanko, Mr. Almighty rocket-guy?"
Carl: "Yep. Ya gotta use all stainless steel hardware, even the hinges on your range box need to be changed out - zinc or brass just won't do - nothing but stainless is acceptable."
L3 Candidate: "Gee, Mr. Tulanko, this seems like it's going to be awfully expensive. I'm concerned that my wife won't like how much this is going to cost..."
Carl: "Wife? WIFE? Oh, didn't I tell you? That's the *first* thing you should have done - get rid of her!!!"
==================================
Seriously, Carl - huge congrats to ya, buddy. Ever since I have known you I have seen you learn many many things, and you have always been one of those people that made a significant proactive effort to pass on your knowledge to others. I know the rocketry community will benefit hugely from having you in an official NAR L3CC capacity.
