Long-time residents know this lesson well: if you park on the street in DC be sure in a storm to move your car so it is not under a big old beautiful tree. The fact is our beautiful trees don't have the root balls to support them in a storm with fierce winds. With every storm over the past dozen years I have taken a photo of one crushed car or another that had the misfortune of being parked under what appeared to be a healthy tree. It's an illusion. Lots of rain creates soft ground. Add to that the fact there are still leaves on the trees, making them top heavy. So, if your car is parked under a tall, and beautiful DC tree, move it now.
