One last footnote. I went to AntennaWeb
http://www.antennaweb.org/aw/Address.aspx
to get a list of digital stations broadcasting in this area. My homebrew antenna receives everything -- including a station 37 miles away. I even get one station that's not on their list.
Lucky for me, all of the transmitters are in the same general direction (southeast). Time to declare victory!
