Turns out the breaking noises I kept hearing were people's windshields in their cars that were parked on the street. Imagine what happened to the people who were driving into the hail going 30mph. There are a lot of tarp covered vehicles in my neighborhood now. We also got a cracked windshield on the car we have parked on the street. We were going to donate it anyway; we just hadn't gotten around to it yet.
We might curse the leaves the that come off our huge oak, but that oak saved our vehicles. Of course, our two-car garage could've saved our vehicles as well. :/
