Years ago while I was driving a local delivery truck I was stopped to pick up some inventory for our store in downtown Houston.
Heard a loud rumble and a pop and looked toward the overpass next to the business and down comes an entire 18 wheeler tire, bounced on the roadway below 2 or 3 times and hit the side of a brick building across the street about 6 feet off the ground. Employees came running out from every exit. Dangerous stuff!
