I contacted Rinehart a couple of weeks ago and she told me they would be coming out with this years schedule in the next couple of weeks. I shot one last year in Iowa. It's a good time. This year he wants to make it a dual shoot. It will be a recreational/competitive shoot. I'm not sure how he plans to work that out.
You can keep checking Rinehart's website http://www.rinehart3-d.com/
If you email them and ask to be put on their list. I'm sure they'll do that and let you know when the schedule is up.
