Hi Mobile 155,
I'm in SoCal as well and I got caught in the rain yesterday too; a little on the ride to work and quite a lot more on the way home.
No biggie though, I just wheeled the bike into the garage when I got home, up on the bike stand, half an hour later all clean and ready to go for this morning's ride.
Cleaning bikes: Just part of life, and far from the worst part!
