Back when I was a kid (sometime in the early 70's) I made a list (no "bucket" back then) of rides I wanted to do before I die based on a list of famous rides in some long lost issue of Bicycling! magazine.
RAGBRAI
TOSRV
Davis Double
Seattle to Portland
Assault on Mt. Mitchell
Paris-Brest-Paris
Hotter-N-Hell Hundred
Now I've done all except the last one, Hotter-N-Hell, which I've just signed up for, so yes, some lists take awhile to complete!
Since I've done the Death Ride (2006), my new list includes Triple-By-Pass and Everest Challenge.
All kinds of fun!
