Late to the game, but count me in. Maybe we start brainstorming on some kind of communications in case we do another convoy? I have capability to use ham radio, GMRS, or CB radio. If a number of folks have the blister pack GMRS radios like you can get at most electronics stores then that might work within a short distance. CB's with external antennas will have more range but more interference. Those of you driving a 5 ton or duece probably couldn't hear a radio to talk on while driving anyway, but might be worth a shot!
