I was starting my path to get my HAM license while listening with my cheap chinese radio. Harvey directly hit my area, something like 50 inches of rain. As the phones started to get unreliable and then NOAA went down, I knew cell phones in a disaster don't mix well. I kind of wish the testing wasn't as "difficult" or GMRS was a little less regulated in terms of hardware. It's kind of a "prepper" thing but more people should learn radio stuff because cell phones aren't your savior.
