Yes, that is the same as what I experienced.
I think early on you may have to give your name to them to be put on a list, but I think to get on THAT list (waiting list) you need to be waiting for the waiting list (haha).
I went I think 3 or 4 hours early but already there were people ahead of me.
They do literally cram as many people in as possible; some were standing room only I think. And just sitting on the floor.
Beats not getting into class at all.
When I went, I think 2 or 3 years ago, they were in the process of producing their own hunting tutorial video, showing field dressing, etc.
Not sure if that was eventually completed and if so, whether we "alumni" can get a copy of it.
