My wife and I will be taking a trip in late march early april that starts off in SAS and ends in FTW. We will be on every Train in the Western Route. I am contemplating buying a no-contract wireless air card for our laptop so we can stay in touch and log our trip.My current cell phone carrier does not offer an aircard option(MetroPCS). I would like to know if this is an option worth exploring or should I just leave the laptop at home and just pen my journal. Is there good reception on all of these routes ,or is reception sparse?Any advise/suggestions will be truly heeded as I've come to find out , You guys really know your stuff!!! Thanks
