When we went. We showed up one year and the place they told us to go to was wrong. They moved the location the morning it was to begin and we didn't know it. Refs were late getting the the game and we didn't have anyone telling us were to go after a few games.
At BYU last season, the 7 on 7 was run much better. We had people and signs directing people/teams where to go. They had also had loud speakers for all to hear the latest instructions.
That was our experience in previous years. I posted last year about this.
