overall, my bike portfolio has consistently outperformed any other investment that I have, excluding property. But I insist, that is not the reason to have that stuff. It is to use, and mess with, and learn about, and wonder about the lunatics that used to ride it in races over dirt mountain passes, and all of the other stuff that goes with it.
and...the cost of all of the bike crap that you fill your garage with won't make a dent
...in the bypass surgery that you'll be needing if you spend too much time on the couch.
