Matt, I had similar problems with some friends of mine. My wife knows better because right up front she learned that my stuff was not to be messed with unless she could guarantee that I'd get it back in good working order. I said it with a smile and a kiss so she took it in a good way. Otherwise she'd have put a knot in my head, lol. Anyway, I told them that since they couldn't return my tools in like condition as when they received them, that they couldn't borrow them anymore. Instead of them going out and buying what they needed, or bringing thier own stuff from home, they simply stopped going camping with us. To this day I don't think they've spent any time in the woods and this took place years ago. I suppose that I could have put some equipment together for them, but I'm of the thinking that if they really wanted to be there, they'd get their own gear.
