We had agreed to meet the other cavers at the McDonalds in Marianna,
FL so as we sat drinking coffee, I overheard the following:
Man in a parka walks in and sees somebody he knows.

“You duck hunters ought to have an orange flag over yer head cuz if I
hadn’t a seen them fake ducks of yours not fling as I came up Idda run
over yer ass.

Duck Hunter: Well, you oughta keep them airboats out in the water
where boats belong and outta the weeds where the ducks hide.

Airboater: I came within 10’ of runnin you over.

They both laughed.

So, is this a real problem? Do airboats run over duck hunters?

I have no idea why an airboat would be on a lake at sunrise with the
duck hunters.
