I look on the tracking site when I hear a plane or copter that's close to me. So far, they're mostly Coast Guard helicopters on training missions. I heard one really loud one night. The tracker showed that the copter was directly above my back property line and following the back property lines in my neighborhood which all happen to be wooded swamp.

I wish I had more time to look at the planes, but I have too many other things to keep up with.
