I usually go with the safari hat. We got 4 of them free at the last Boy Scout Jamboree (they have the national guard logo on them). It covers the areas that I have a hard time getting sunscreen on.
I also look horrible in hats, but hey, I'll never see these people again, right?
I can't use that argument at scout camps (we live in a small town environment). I've definitely seen lots of people I work with who often DON'T recognize me!
