I have a trainer and rollers...and I live in Southern California. I hardly use either one right now, but I did use both of them several times last winter and even in the evenings. But we hardly have any rain so I don't have a problem riding when I want on the weekends (can't ride during the week because I usually get home too late).

I have to fix up my old bike so that I can make that my trainer bike--otherwise it's just too much of a pain to haul my bike up from the garage (1 level below my living room), put it on, and take it off.

I wish I felt safe enough to put my rollers in my living room (next to my 9 ft glass sliding door)--that's a lot more interesting than the trainer.
