Nuff said.
I don't intentionally ride in the rain anymore... However, I do have a jacket/pants/helmet cover if I happen to be on an organized ride (where I don't get to pick the days), or if I'm 'on tour' for more than a couple of days (damn unpredictable weathermen!) I've never tried a rain cape, but I did wear a garbage bag once...
