Are you guys freaking NUTS?

Hell yes.  We must be!  Nobody else we know does this every weekend!  Sure, there are a few insane, oops, I mean brave souls who are coaxed into plunging into these vertical maelstroms on occasion (That's why we bring video cameras :0) ) but,

NOBODY DOES THIS EVERY WEEKEND OF THE YEAR!!!

maelˇstrom, n.

1. A violent or turbulent situation: caught in the maelstrom of war.
3. A whirlpool of extraordinary size or violence.

What is your longest rappel to date?

That would have to be El Capitan, in Yosemite National Park, CA at 2,650 feet (That's a half-mile in case you are wondering).

But it didn't have any water running down it so it was just 'ok' I guess. :O)

What is your longest wet drop to date?

That would probably be Incredible Pit, Ellison's Cave, GA at 440 ft.  And it was 17 degrees outside.  My cave suit was completely frozen by the time we got back to Mole's van and I couldn't take it off until the laces of my frozen, muddy boots warmed up enough to untie them.  Or so I thought.  My laces had broken sometime during the trip but were so frozen together that my boots stayed on my feet!  It took 45 minutes for my boots to thaw enough to get them off.
