Just got back yesterday afternoon from a 9 Day trip from SE Minnesota to Yellowstone & Grand Teton National Parks. Full 3G where we stayed at Jackson Hole. Drive there and back through South Dakota and Wyoming....not so much. Lots of miles with no service. Lots of miles with signal so bad that it wasn't worth the time trying to surf the web. Read magazines in Zinio, read part of a book in the Kindle app, kept a travel Journal and played games while on the road. Always had wife where we stayed..
