Yes it is open to the public. There are a few vender stands, not sure exactly what will be there in that way, seems to change from year to year. Also food is available, red bull will be given out free and there are shirts for sale. Thursday is the best day, I think. There is a tower scramble event which requires running about 125 yards engaging targets, running back, climbing to the top of a three story structure and then rappelling down. The sniper is involved in that as well and has to climb to the top of the second story of the stucture engage a small target 100 yards away which activates a moving target. Then in the second half of the day the obstacle course, which to look at you wouldn't think much of, but it is tough. This year we have teams from Indiana state police, as well as a few army teams. I think there are around 18 or 19 teams. The public is most definately welcome, and it gives you or them a chance to see teams from around the country compete in various events that incorporate parts of what really happens within the aspect of a game. Hope to see you there.
