Must suck to have a winter where all you have to dread is rain.

Hefty bags might be better. Market bags definitely have tiny holes poked in the bottom for whatever reason so they absolutely suck as rain covers. My Brooks cover was great for riding because it maintained the shape of the saddle, no awkward plastic flapping about your nethers, but I wouldn't really count on it to repel water for too long when left out without a rider's bottom to shield it. I haven't had experience with Hefty bags but I know shower caps work well and they have elastic edges, 2 work better!
