Well, I don't actually ride all 30 of my bikes though I plan on it someday. If I come across a bike that has all origional rubber on it I try to get it to someone who likes that kind of thing.
I like to see that kind of stuff, I know a couple of LBSs that have some sweet old stuff hanging on the wall. I can look at it all day. My rides are practical(ish). Maybe whin I'm rich I'll get something to hang on the wall.
