Gee, Mostly out west there are microwave towers across country for the long
distance, and I suspect those also carry the backbone for the cells now too.
I dont see many MW -only towers around here thogh. Mostly its fiber cable
here too, that I see running all the way up to D.C. I hope they have
viable backups. I know we are getting more and more cells towers around
here - sometimes within a half or quarter mile from each other. You would
think they would share those things, considering the costs.
