When I got back closer to the house, I had to come nearer the commotion. They had completely shut down one side of Wendover. The fire engine was still there, with about four or five police cars, two officers directing traffic, one fire department SUV, almost a dozen city vehicles (cars, vans, trucks, big trucks), a bunch of civilian workers in orange vests walking around, and three news crews. I tried to get a look as I crossed Wendover, but couldn't really tell what was going on. When I got back to the house, I kept on going and jogged down to Wendover to try to get another better look. The only new thing I saw was part of a car -- a wheel, a front and rear bumper, and part of the rear fender. That's when I figured it was probably a traffic accident -- and it must have been pretty bad to have broken a car in that manner.
I turned on the local morning news in case they're reporting something, but so far, they aren't.
Edit: The guy on the news, before breaking for commercial, just gave me a clue to what happened: "We've got a major story in Greensboro. A sinkhole on what may be the busiest street in town, and we've got your coverage coming up."
