Verizon vs. ATT

During our stay at Sleepy Hollow and Indian Lake State Parks, as well as, the campground we are at just east of Marquette, we have found that we aren't getting any bars on our ATT service cell phones. The interesting thing is that in all three places we have gotten excellent high speed internet with our Verizon internet plan. When the ATT phone plan comes up for renewal we'll be switching our phones to Verizon!
