Wow! I didn't even know they made underwear like that! That is really good to know. As for bathing in the field, well, my little brother summed it up like this: face, feet, crotch and pits. I love baby wipes!
I am keeping very quiet now as the other company on my floor, to which my roomate belongs, is having a gi party. And seeing as how I was allowed to escape the field for a night, I am going to enjoy a hot dinner and stay safely hidden until the danger dies down.
