True enough, myr, but don't forget it all RF and, therefore, basically LOS. I recall that Idaho isn't too flat.
Lots of good mountain peaks with commanding views of valleys and plains. A WiMax tower at the south end of Pocatello would serve the whole valley including the big gap area around Inkom. Much of the center of the state is very flat Snake River plain. The major cities are along interstates I-15 and I-84.
