It's hard to find a place in the US where your NOT in range of a
repeater. And, even if you do, repeaters are only ~$200 to set up.
APRS is a good, solid and cheap solution with 1min fixes and all the
additional data we'd like to see. APRS would really let the folks on
the ground see the real-time "play-by-play" progress of the fleet out
on a task.
