OK. ;) Many years ago I was several hundred feet up the sheer granite face of Glacier Point and needed to pee (coffee, not fear). In order to drop my jeans, I had to completely undo my climbing harness and hold on to this scraggly little tree with one hand. Needless to say, it wasn't quite safe... nor did the little tree provide much coverage. "Exposure" is a climbing term, but it usually refers to amount of air if freefalling, not one's naked netherparts! I found a small company where the lady sewed trousers for outdoors-women with extra-long zippers going all the way around. Great for skiing, too! However, there is a problem with zippers going through the crotch unless space has been built in. (I think the technical term is "rise", which seems illogical.) Given how sensitive men are, I had to wonder about zippers there. Back in the days when gentlemen rode horses, the trousers had extra bagginess in the butt. It wasn't stylish, but bursting a seam when mounting wasn't stylish, either. Tailors just have to accomodate egos and practicality both. Carolly
