Lake Mead. It is largely contained within the Grand Canyon National Park one of the first national parks at receives more that 4.5 million visitors per year. This glass Skywalk opened in 2007 which allows visors to view the Canyon straight down thousands of feet.
You will have to enjoy the view without being able to upload your favorite photos to Facebook and Twitter because cell phone reception in the canyon is almost non-existent. One would think with all these visitors and the "broadband stimulus" from Obama Administration that this National park might be on the list to provide wireless reception for your phone for safety? Cell service from Verizon, AT&T, Sprint and T-Mobile is hard to find in the area. We would appreciate your contribution to the Deadcellzones.com map of areas where you found reception in the park.
