We used a couple of small hand held radios on our trip to Az this fall. The reason we brought them is because we took two vehicles this year. They are aaa powered and we just turn them on and leave them on while traveling. We use them because the cell phones don't always have a connection. We don't use a busy channel.

I was born with nothing and I still have most of it left.
