Thanks y'all for all the tips,. they'll most definitely help. My friend is a pretty avid camper (he's an Eagle Scout) and isn't really into the whole bring-everything-but-the-kitchen-sink method of camping... we're going to be very minimalistic. Meaning tents, no camp site, no showers... I think the best I'll get is a stream, which will be fine. Luckily for him, I'm not high maintenance in the sense that I'm not going to complain if I feel gross.
Is Certain Dri that anti-perspirant (sp?) that is supposed to be prescription strength? I've used it before and it really really does work, but I had no idea that it could cause cancer!
More than anything, I'm super excited for this trip and my big adventure outdoors

More than likely, he's going to be 10 times stinkier than me!
