The best thing about this hobby for a "non-boomer" is that all of those "boomers" bought all of those bikes way back when, rode them around the block five times, and then abandoned them in favor of the next fad.
What a score when you clean up a 45 year-old bike and realize there isn't even brake rub on the rims! Brand new vintage bike for a fraction of the cost of a brand new modern bike.
Actually that's kind of sad.
