I just looked at the cell phone coverage map and was a bit surprised where they claim there is coverage for Verizon. Places like just above Bunnel Cascade, Merced Lake, much of the Lewis Creek trail, west end of Bernice Lake, Vogelsang Pass. I can see where Vogelsang Pass might be good but I thought the goat once said that was not possible. Apparently anything remotely visible from Sentinel Dome is getting limited coverage? Also, where is the tower for Tuolumne Meadows area?
I had not planned to carry a cell phone because I didn't believe it would amount to anything more than dead weight. The only reason I might consider it is to reassure my wife 3,000 miles away that I'm O.K. while hiking alone. For safety sake it will not work in the only place I plan to be off trail.
