Cell phones no longer "active" CAN be used to dial 911 (and also I think Customer Service for the nominal carrier, I *think*).
My use though is as a info store of "how to" procedures. And entertainment. The rf bag is just in case it is "that" sort of event.
Border Patrol, you can freely purchase a ham radio, you just can't legally USE it until you get licensed. It isn't all that hard to get licensed. There are threads on this site walking you through it. A good, VERY inexpensive handheld is the Baofeng UV-5R (About $25 on Amazon - use the comm2a link!). It isn't the BEST radio out there but the price is right and it's great to learn with.
