Mr. Kobos,
Bring what ever gun you shoot the best.
In the past there has been a sporting course and two five stands (mix of close and some medium distance targets).
There is no restriction on spreader loads that I am aware of.
You register for the sporting clays events either a head of time (use Deep Rivers website) or you can do it there at the club house.
You sign up for the Challenge Events (hammerless and hammer event, remember there are two) at the Parker tent. You pick a time to qualify.
You sign up for practice at the five stand field as you want to shoot.
I suggest you read the rules for the Challenge event ahead of time.
Good luck. I hope to see you there.
Go team Parker
