Good article on the non-HAM side of communications. I got my HAM license a year ago, installed a mobile HAM radio on my motorcoach and picked up a few handhelds. I still don't know what I'm doing so I maintain a collection of resources on communications and have added this article to the list. The radios I use the most are the cheap little FRS units. My wife drives the car and I drive the motorcoach and with these little radios we coordinate our moves through traffic.
