speaking of things flying off trucks and hitting vehicles... on the way home from a regatta this weekend we saw a whole wheel/tire fly off a 3-axle enclosed cargo trailer being pulled by a big truck. The tire hit something, bounced up in the air OVER a pontiac sunfire, and then started rolling down the hill on I85 just north of Charlotte. Thing is, it was rolling right down the white dash line in the middle of the highway. We had to pick our slot to pass it given the 8'6" wide boat we were hauling. Glad it didn't cause any damage to anyone.
