no I have not been, is it worse or better?
I went to a DUI rally; my experience was...interesting.
I and a bunch of n00bs (about eight of us all told, including Dad, Mom, 20-ish daughter, and daughter's boyfriend) were sent to a dock, where we stood in the shallows and waited for an instructor to arrive.
The instructor didn't come and didn't come and didn't come, so I got bored and switched into lecture mode. I told the others how the drysuit worked, gave them tips on how to inflate and deflate and maintain buoyancy, instructed them how to route and connect their hoses, and so on.
Finally, the instructor arrived. "Hey, welcome, add air here, let it out here, let's go dive."
Splash. The group got waaaaay more out of me than they did the official leader.
So we proceed to dive. Mom couldn't control her buoyancy at all. For about five minutes, she's up, down, up and then rockets
downdowndown to 60'. We all go after her. The instructor catches Mom and gets her sorted out...and then does a headcount. We're short one. Daughter is missing.
The viz is crap that day. Ohhh boy...
We beeline for the surface. Daughter is sitting at waterside, out of her drysuit. She got a suit squeeze and bailed about two minutes in, but nobody had noticed.
So yeah...it was interesting.
