"What do you do? You squeamishly go looking for a quiet spot behind a bush to do your thing. You cautiously avoid the poison oak and ivy. As you carefully squat down and try to relax a snake suddenly comes slithering through the weeds and startles you. What a mess!" Oh, Lorna, that was terrible! I bet nobody rear-ends his truck (or even follows too closely). The problem is that most of us can avoid the poison oak and curled-up snakes... it's the mosquitoes which make a quiet trip to the bushes difficult, and this device won't curtail them. The other problem is that one would have to drop one's trousers on the road, and passing motorists would perhaps have something to say about the view. Nah, I'll take my chances behind a tree. Carolly
