Funny thing I just ran across this. Just picked up a "Stranger things" Mongoose repro. I had dozens of BMX bikes as a kid since we were always trading frames, forks, and parts, but I never had a Mongoose even though I really wanted one.
If you are into vintage BMX, I had an Ashtabula in 1977 or 1978. An unbelievable heavy, multi-gusseted piece of steel. By 1979 or 1980 no one wanted something like that (everyone wanted a Red Line, DG, or GT) and I couldn't give that thing away. Today, that is one of the more sought after vintage BMX frames. I can't even remember what I did with it or how I got rid of it. It is funny how things change over time.
The green Schwinn Stingray is an exact copy of the Wheelie Kid's (Mark Mandeville) bike from the intro of On Any Sunday.
