Thats why I went with a handheld CB over an FRS or GMRS, since I already have one in the truck if one of us wants to get out at a rest area and talk back to the other its much easier to just grab the handheld CB. I found an older model that had a removable battery pack on the bottom and that pack opens to hold AA's so I have two packs stocked with Syano Eneloop, I've never drained one pack yet even when loaning it out to someone else so we could talk back and forth between vehicles on a road trip.
