I don't worry about my bike at night, either being stolen or being rained on. As far as security goes, I chain it to the picnic table or a tree close to the tent. As far as the weather goes, bikes commonly get ridden in the rain - commuters, tourers, etc. So rain on the bike isn't an issue. The only thing I do is put a plastic bag over the saddle. Ever sit on a soaked saddle? I prefer mine dry. When I've ridden in the rain or had my bike sit out in it overnight, the chain usually needs to be oiled soon. I carry oil.
