Sshannon, here's the same old saw - GMRS has very limited range in most conditions. Without being on a pointy mountain top, a hand held usually has a mile or less range, a vehicle mounted mobile might have 3 or 4 miles range to a similar vehicle. For effective use, learn if there is one or more repeaters in your area and learn if you can become authorized to use it. If so, program your radio to use it and figure out where and when its useful.
The best advice is become licensed and use it. In some areas it will be a good standby and alternate comm mode, in other areas it will be completely useless. You won't know without using it in situ and no one can really tell you EXACTLY how it will work for you and YOUR locations.
A lot of people say they want something for alternate comms if cells are down - if cells are down, most repeaters will be down too and many GMRS frequencies will be flooded with people with little or no knowledge of using a radio.
In my area there ARE several well located repeaters on commercial towers with backup power, but in reality, its rare outside of MAJOR metro areas. There are many repeaters here, but almost none have back up power and most are poorly located. Out of 50 or 60 around here, only 3 or 4 would be useful.
