Watching this on Vattastic, much of what I see looks nothing like any of the procedures from the NOTAM (e.g. the direct VFR arrivals from the East??). If y'all would like, myself and several others on this forum have flown in to Oshkosh a number of times for Airventure and would be willing to help mentor/train controllers on Oshkosh procedures prior to the event in the future.
I know we have at least one controller who has controlled it for real, as well, and may be willing to provide some guidance.
