I did my advanced open water class on travis and went to 110 feet for our deep dive. It was pretty surreal down there. Your rum will definitely be chilled.
The instructor had us try to do simple math problem while we were down there on a slate. Simple problems like 27 + 62. I am a math boy, but in the 60 seconds he gave us I could not do a single one. He point was "you are stupid at that depth". Good lesson I will never forget.
He was a great instructor.
Dude, I'm stupid up here! What's the visibility that deep?
