I used to have Sprint and when we would stay at the Bush, I would be the only one to have cell reception. That's because back then, Sprint was an ASC sponsor and they put up a couple antennaes - I know they have them at the top of Northridge - maybe top of LP, cause I never had service off the mtn. Now I got VZW and have very little anywhere in the Valley. Bummer - but I can go a few hours without using my phone. After all, I live only 10 mins north.
VZW is on-again/off-again as for coverage. Just when we think they're concentrating on one corridor, they switch us off to another. Though their main goal is to get off Unicel on 91 south of WRJ. Many of those sites are still in the permitting stages. These things take time.
If its the case of VZW can't do an island site for SB, I don't see them ever coming to the Valley. I don't think a tower through Granville Gulf will be easy to get through the permitting/enviros/etc.
Everyone wants their cell phone to work but noone wants to see the tower.
