Just left Airmans Cave tonight. It is my third trip in. I have 2 experienced grotto members who have showed me the way. My first trip was to the Aggy Art Gallery...2nd trip was all the way to Poetry Passage where we were confused on where to go so we turned around. That trip took all of 4 hours. I am a small guy who can squeeze through tight places pretty well. Lots of tight spaces... Very advanced level cave and I do not recommend going in without proper equipment, food, and water. Planning a trip to the end on Jan. 3, 2009 with some experienced cavers. If you decide to enter Airmans, be READY!!! PACK IT IN, PACK IT OUT!
