1st Waterfall of the 1st Rappel....Things are looking good here, but....This Gal slipped twice and ended up getting Pounded directly in the Face both times on the way down and that's not a Good Thing...She swam across the Pool erratically and was having trouble feeding the Rope through her Device...She was pretty Shook Up and almost went over the 2nd Fall backwards and headfirst which would have put her Upside Down with no Way to Breathe...It could have been a Nightmare.... Somehow, even though she was almost over, she heard us frantically whistling and managed to pull herself back up just before the Point of No Return....There was a Panic Attack after that, but we got her Down....She Recovered Nicely and was Fine after that....
