I haven't encountered any shady types around here yet. Just a bunch of great people with a passion for these bikes. The Cabe is a great place to hang out. The only things I would watch out for is the old bike addiction and the tendency to spend a fair amount of time and money on it.
I really like your frame. Is it all aluminum? I'm looking foreward to seeing what you do with it. That's going to make a real sweet looking rider. I'm building a '30s Newport from the frame up for my girlfriend with a bunch of different parts. Just gathering parts right now. I started out to build one old bike for myself and now I'm doing like 5. Love it! Best of luck with the project!
