I've been hunting around for another century to do after LRRH because I really like how having an event to look forward to gets me out the door even on days when I am, by all rights, way too busy to be riding. I've come across several centuries that are described as "self-supported." Why would someone do a self-supported century? Isn't that basically just like any other time when you go for a long ride? What am I missing?

I'm also looking for recommendations for really great centuries in Utah, Idaho, Nevada, California, Arizona, Colorado, Montana, Oregon or Washington. Any recommendations?

Thanks.
