We were at Mammoth Lake today. I saw Driftdiver there also teaching a class.
Vis was 20 feet and temps were 88. The coldest it got was 87.
We had a 93 minute dive and a 92 minute dive.
You have got to go into the C-130. They added a skeleton in the pilot seat and a coffin in the back of the plane that says "Do Not Disturb" or something like that. When you open the coffin a skeleton sits up.
We also practiced our buoyancy control swimming through and under everything we could find - C-130, centipede, yellow submarine, pipes, towers, boats, etc
