Attack of the Shopping Cart

There are several scenes in Attack of the Killer Tomatoes where you can see tomatoes on wheels, and I believe there's even one instance of a tomato in a shopping cart (but I could be wrong since I haven't seen that movie in a long, long time). I have to say that I can relate to being chased by a shopping cart. It has actually happened on numerous occasions, most recently this past Sunday. As I was driving through the K-Mart parking lot, I saw a cart coming from the side, booking it in my direction. It wasn't pushed by anyone, and it wasn't windy. It was just going at a good clip, and had I stopped to watch it, it would have hit my car, and in fact, I had to step on the gas to avoid it. I have no idea how it got going, but it did and it was moving in a nice, straight line. It reminded me a little of Missile Command for the Atari 2600 where you can see the attack coming from a mile away, but may or may not be able to stop it. In this case, I was able to avoid the attack, but I know that it is only a matter of time before I don't...
