One thing they might not notice working in California.<p>Down east we have trees. Not shrubs that pass for trees, but 40-50 ft high trees that add 40-50 feet to the height of your sticks.<p>(Yes, some researchers have gotten millimeter waves to reach base stations that are under a canopy, but that is different from the tower which will have to shoot through quite the slant angle unless it is solidly over the treetops.)
