My husband and I are looking at taking a trip to Red Rock Amphitheater near Denver, Colorado. My mother who is 90 and in a nursing home has not been doing well and I am worried we won't get a signal while at the concerts there. Can anyone tell me what the signal is like so I can call home to check on her or receive a call from a family member is something happens? Thanks for any info I can get.
