As one who has just returned from camping, Mammoth Caves NP and Blue Ridge, I can say that cell service is most definitely ubiquitous, neither are Star Bucks. We did find one coffee shop with free WiFi. Of course we weren't looking very hard. About the only thing I needed my laptop for was storage for my camera cards. Leave the internet at home, it WILL be there when you get back. BTW, ditch the RV too much more of an adventure in a tent.
