I spend almost as much time getting rid of bikes as I do actually working on them. Being a frugal old Yankee, I can't seem to let anything go that has even a shred of intrinsic value, hence I tend to become inundated with bikes and parts of all kinds. The old adage of garbage-in, garbage out is taken quite seriously here, and I cull my "herd" on a weekly basis. I am constantly struggling with it.
Just yesterday I had a conversation with my wife about it, and I've decided to up my game a little - seeking out and retaining only bikes that really flip my switch, and letting go all of the others.
