Raincovers are they worth it?

[Brushy Sage]

I always use a rain cover, even when there is 0% chance of precip. For one thing, it is such a terrible decision to make when you hear thunder and see approaching clouds. Should I stop and put it on? Will it pass with just a few drops? If it is already in place, nothing to worry about. The other thing is that it protects the pack and its contents from damaging sun. Rain covers are not so expensive that you can't replace them when they get worn. I use Campmor's.--Kinnickinic

Neat idea. Also, I'm wondering if you were backpacking during the snow the past couple days.
