Do you have the locations of their dumpsters 
where they throw out goodies that they're tired of storing?

Clouds?? Who said NLOS involves clouds? While 
some might say clouds are the only practical NLOS 
mode (where 2 way communication has been 
completed), NLOS is a broad category that could 
involve knife edge refraction, airplane scatter 
or reflections, refractions or ducting that exist 
in the atmosphere between the ground level and the edge of space.

Water vapor is the primary scattering mode in the 
atmosphere at visible wavelengths, so the dry air 
that exists there is a blessing, not a curse. I 
think other states might have long line of sight 
paths as well, but that they are not usable for 
optical communications because of the water vapor in the lower atmosphere.

Welcome Terry, ask on the list, I think there are 
a few laser people in AZ. And send some of that clear air eastward please.
