A poster on rvparkreviews dated 4-2013 reported excellent Verizon air card signal at Point of Rocks. I dug back in the comments quite a few reviews to come to that nugget. Rvparkreviews should have a category for cellular reception even if it is beyond park control. It is very valuable info.
It pays to read reviews and travel blogs using google search to see if you can find this info. I'm completing a two week trip to rural Utah and found Verizon data coverage to be very spotty in places like Capitol Reef, Loa, Koosharem, Torrey, etc. There was basic roaming coverage at times but no data available.
