As Shaman say ATT has it solid coverage in that area. For me, except for those 45 days a year when I am in the area Verizon is far superior. Plus it's a corporate plan so if I opt out it would cost me a lot. On the other hand we have a land line at HQ that we really never use that is costing us $600 a year.
Once I was in Tahawas trees and my phone rang, kinda surprised the hell out of me. The cool thing was the skiing was great and by taking a 20 min call in there I was able to extend my vacation 3 day.
I have one bar above 2500 feet and for me texting to connect with people (Zelda mostly) is far preferable to those obnoxious radios we were using before we able to text. Often time texting is about "hey I want to take two more runs...cool?" Worth it.
