I was told that the July Canton Ohio regional is scheduled to be the Friday, Saturday, and Sunday leading up to the Camp Perry NRA nationals. Camp Perry events begin on Sunday and would then over lap if that happens....
If you leave Canton Sunday after shooting it is only about a 2 hour drive to Camp Perry, so you should be able to check in Sunday evening.
If you are not a Master or High Master, you won't be on the first relay, so you can show up early Monday morning, check in and get your packet.
If you are on the first relay but can't get there in time, you can infiltrate another relay. The Range Officials are very accommodating, they want us to be able to shoot. Go to the CRO (blue shirt near the tower) when the next relay is called to the line, explain and ask if you can shoot this line. They will point you to one of the ends and tell you to take the next open spot.
I really hope the CMP/OHNG and NRA have extra hours for in-processing and packet pickup on Sunday night and Monday morning. They have created a ***bleep*** [bad situation] and should take the initiative to help shooters as much as possible.
