A friend of mine had a mandolin split open when he was camping and got caught by an unexpected cold snap. I don't know what your climate is but, I suppose, check ahead for possible temperature extremes. Not that you wouldn't, anyway, since you have to be prepared for them yourself.

I'm the one with the $75 guitar. I would be mad if something happened to it but I wouldn't be heartbroken. Cheap, unromantic instruments definitely have a purpose.
