I'm very curious about this as well. I am headed to Yellowstone and 
grand Canyon and was trying to figure out if I would be able to get a 
mobile hot spot and find activities along the way? Has anyone tried 
these in the Great West?  I hope it's okay to jump into this question, 
sorry if it's not.
