What a riot--Sheepish, I didn't even notice that I don't use any of them either (ok, I confess, I always end up buying those little Pepto Bismol tablets when I get a little too loose while travelling in Latin America, and have to take a long bus ride without a bathroom)(posted 9639 days ago)I use gasoline, too, dang it. I don't use much, but I'd use a lot less if there were bus or train service to my area.
