Just going up to my sons from CT to NY state in separate vehicles made it nice. Heck, we talked more on the radio than if we were in the same vehicle. I had my mobile in the truck and set up an HT with a microphone and an external antenna for the little lady. Much easier to pick up the mic and talk than it is picking up the phone, dialing, waiting to be picked up etc. I don't think we were ever more than a 1/2 mile apart.
