I love riding in the rain, and the thunderstorms around here are not too bad. I just keep riding. The hail is irritating but not horrible, though I've only ridden in pea-sized hail so far.
I don't take cover because where I ride there IS no cover. I'm riding through fields with no buildings or houses. Getting under a tree is worse than nothing.
