BADGER HERE, definitely getting a little hairy down in this one.it looks like it could be 35 to 40 feet and I was in it pretty darn long but with the fan going it was okay.there were times when it felt like not much air was in there just wish some good stuff was coming out.the ladder is only 32 foot so we might need to rig something but I don't like that when this deep.one last attempt with this one next week we need something good to appear.like rick said the pictures are cool though.i did keep 2 1915 cokes and a Bethlehem,pa. clear coke with the ribbons on it(don't know what type this is,but will try to post picture).
