Socks

I'll bet you don't have as many socks in your bug out bag as Oregon Mike has in his backpack.  He uses socks as little mini pack bags in his backpack for camping, and so forth.  I think that in addition to extra socks for wearing, if worse comes to worse, you could have lots of extra socks to spare if you follow his fine example.  Hope his fiancee doesn't do him an injury for absconding with hers.
