Rob, it's a large tournament that has been going on for a few years now. We don't play in it, but instead compete in the West Coast Summer Series, which is held a week earlier in the same area. The Summer Series gets about 5 western Washinton teams each year, in addition to a bunch of California teams and a few from other states. You'll find guys who like each of the tournaments, both have good reputations. Great venues that time of year. Lots of people make it a family vacation. One thing to possibly consider with USABF, it conflicts with the Area Code Games on dates. I don't know if that applies, but it might be a consideration.
If you're looking to put your son on a team, you might want to look into some of the Washinton teams near you. Also, please PM me so that we can talk more about this. I'd like to talk to you about some things I don't want to post here.
