The parking lot is on a very gentle incline, but I'm still not clear on how the bus could get rolling like that, especially if the parking brake truly was set. I wonder what became of all the shopping bags and luggage that were probably stored in the bus. Oh well.

That's not all, though. A few days after the bus rolled into the river, a barge going upriver sank. That, too, is a first in my experience. Here again, the crew claims not to have any idea why the barge sank, but my guess is that it was overloaded, as many of the barges tend to be. It was carrying sand, and it was probably loaded down all the way to the water line. A few waves probably washed over it from passing boats, and put some water into the sand, which of course made it heavier. From there on it would be a vicious circle, with the boat sinking deeper and deeper and taking on more and more water.
The moon was full during one of these days; maybe that had something to do with it. Lots of weird things seem to be happening lately.
