OK-I'm in for the May 10 at Kiowa Creek. I am also a member there so that makes at least two of us. I'll give them a call to see if they have any organized events going on that day. I know there is not a registered NSCA shoot that day at Kiowa because there is one down at Pikes Peak in the Springs. K.C. does offer discounts to guests so I'll try to find out what the rules are on that. They typically cook lunch on weekends regardless and it's usually about $6-$8. The menu varies but it might be bar-b-que, hamburgers, brats, stew, etc, with chips and a drink.
I would vote for 100 rounds. I'd be happy to shoot more if you want. If you havn't been shooting a lot recently, your shoulders will probably be ready for a rest at 100. They do have 24 stations. The ones past #10 get more difficult quickly as these are usually the stations they do the registered NSCA shoots with.
Shoot me a PM if you havn't shot any sporting clays and have any questions about guns, chokes, shells, etc.
Looking forward to meeting up with you guys.
Tom
