This is what happened. I came home last night around midnight right after a bad storm. My road is a long dirt road with trees hanging over it so I had to stop to pick up limbs that fell in the storm. While moving a limb I heard a loud bang on my truck. When I turned around to see there was small rock sitting dead center on the hood. There was sand around the rock where it landed. This is a local rock so no meteorite. Also it appears to have landed straight down because the rock did not bounce or slide after hitting the hood like would have happened if someone had thrown this rock. Just the rock with a little sand around it. The size of the rock is about one inch x 3/4 inch and about 1/4 inch thick. I'm thinking this rock was placed on a limb over the truck by a squirrel or bird but this still seems weird. Any ideas?
