Thanks BZH. I've wondered about repackaging them and if it makes the food "stale", but I suppose that's really a non-issue since there's no water there. I'll definitely give that a try.

I'll look at those other options you mentioned as well. I have considered taking with snack foods such as almonds and beef jerky, as well as Clif bars. Not yet tried those, but I imagine those are good alternatives, too.
