Day trip Recommendations

Is that with AT&T and Verizon? Or is one better then another?
Occasionally get text messages. Probably need about a 15 to 20 min drive back to top of mountain for consistent service.
I find this to be the case in any of the gorges in PA where I happen to be.
I don't recall ever having any service back along penns in the Poe area. I have AT&T. my buddy gets a signal as we exit the tunnel on the gravel path but it disappears quick.
Awesome, thanks! That gives me a good idea of what to expect.
