Kevin - great insight there. Thanks for the suggestion!
Dale - A few thoughts on what you said:
I bought the unscented Dr. Bronners to give it a shot. I'll probably try it at home soon to see what I think. If not, I'll go with real toothpaste + hand sanitizer.
My trips will be 2-3 nights every 1-3 months, so I can pick and chose time and location to avoid major snow and rain storms. I will indeed keep in mind what precautions I need to take for clothing, hydration, etc should the weather turn for the worst. Thanks for the heads up. This list is assuming favorable conditions for the southeast: 20-30 F at night, 40-50 F during the day, rain being very possible.
