So is that why they ain't got 'em in thir. I guess that makes sum sense, don't it? But, if there ever wuz a big tractor trailer that jacknifes on the interstate, it would be handy to have a band-aid around to help uthers. Although, if someone's leg is crushed under a truck, I don't know how good a band-aid's gona do. .....just some nice thoughts. Later, Dan
