in reverse order of importance to me, personally:

1. You have to place in a bunch of races to upgrade your bike racing category.

2. This winter has been the driest on record here in Tucson.

3. If you watch a bike race in Phoenix on Sunday, ride hard on Monday, and hang out outside the downtown Starbucks for twenty minutes before going to the grocery store on Tuesday, there is a distinct possibility that you will sleep twelve hours on Tuesday night and wake up at 10 am on Wednesday, completely missing the trash pickup, which usually occurs around 9:30.
