mccabejc:Dude, I was trying to be humble !!!!
Anyway, I figure that some of the shots must be staged. For example, it's hard to believe that first the cameraman squeezes his equipment and himself thru this tiny opening (all the while kicking up clouds of silt), and then they have to wait for the silt to settle before getting a nice clear shot of a diver coming thru ??? I don't think so. They must get the shots at another location, in an opening which is easily accessible from either side.
This whole thing just blows my mind.
It looked like the Alachua Sink area to me. There's a Sonny's BBQ right there and a double highway just like in the video:

These guys are pretty good and I doubt seriously that very much (if any) of it was staged. Cave diving cameramen are just like the cameramen who film mountain climbers or, for that matter, Ginger Rogers. She did everything Fred did only backwards and in high-heels -- the same goes for the cameramen in this documentary. Really exemplary work!
There is a second installment coming out this month on PBS:

Cave diving, as many here know, is an unusual offshoot of SCUBA that requires a great deal of discipline, training and equipment to do well and safely. Not everyone who does it does it well or safely, just like in regular SCUBA, but there are some very talented folks out there that make it look easy, like Wes' team and the WKPP folks who have climbed the Everest of cave diving not once, but used to do it in their spare time on weekends without serious incident:

It's all about focus . . . .
