IBO 3-D shoots are not really set up for spectators. As a matter of fact I think you have to pay extra to have a family member or friend walk the course with you if you are shooting. The only thing you could watch is people on the practice range, and of course you could visit the many vendors boothes. If you are going to travel all the way to Nelsonville, and assuming you have shot 3-D before, I would encourage you to go ahead and shoot. Its alot of fun and you will meet some great people with the same interest as you.
