I just moved, have DirecTV scheduled to come out tomorrow to install, and I'm very unsure that I've got line of sight to the satellites. Is there any sort of online map, like Google or mapquest, where you can put in your address and it'll show you a line of where the dish will approx be pointing? I know I can go out and buy a compass, but if there's something online (similar to antennaweb.org) that'd be great!
