David,
I did flight line safety on and off 2 or 3 conventions. It was OK, and I
liked riding the scooters back and forth on the flight line trying to
look important! I'll give it some thought about doing it again, did
flight line ops last year and enjoyed that, but they do kinda shut down
during airshow.

Probably the only downside of FLS was explaining why there was zero
tolerance of feet and stuff over the fireline ("Because its for safety,
and its the rule!").
Always thought that zipping along the flightline with a sickle swinging
along would get the message across....
