The wheels on the bus

Ok, Yesterday my kids weren't home from school, like 1/2 hour late. Come to find out that the bus has to turn around at several stops (including our house) and it can't drive straight in and then back out. It has to back in to the turn around and drive out frontwards. So the bus driver, which is a really good driver, backed into the barrowpit and there was stuck until the jr high bus came along and all the kids got off of the elem bus and got onto the jr high bus and got home. I've been thinking about this and I've decided that the bus needs to get those cat tracks on the back tires so that it won't get stuck so easily. Wonder if Kim Haws could invent something like that??
