Our boys came back from the Baseball Nationals (same people, same facilities) in late July. Potentially the best tournament I have ever been involved in. By far the best facilities we have ever played in. My only complaint is the cost of the tournament. If that's not an issue, there's no reason not to, in my opinion.
Bump, because I'm curious about this as well. Looking at either KY or TX in 12U next summer. I don't like that the TX tourney is so early (beginning of July.) We'd still want to play ball after that but couldn't justify another road trip.
