To get a "National" event launched, I think someone would have to step up to the plate and become the event coordinator and make some calls/emails to
smartUSA and to some of the guys that organized the Wisconsin Dells outing. Just like asking the NFL for a Super Bowl, get a plan together and send a proposal to smartUSA. Also, contact the vendors here on SCOA and SCOA itself (aka Ryan) for assistance and maybe some sponsorship.
Once you get a group together, you could start searching for a site, such as the Kansas Speedway. See how much it would cost to rent out the facility for a day or two.
IMO, we would need a place to gather for a couple days worth of activities and also plan trips to local establishments, such as the Negro Baseball Hall of Fame, Kaufman Stadium, Arthur Bryants, one of the casinos perhaps. You guys know more about the area than I do, but you get the idea. Put one person in charge of each venue and the participants can sign up with each event they would like to go to.
But again, I would think that the FIRST thing is to get a group of you MO-KAN guys together and approach
smartUSA about hosting a "National" event.
GOOD LUCK.....if you can pull this off, you can count on US being there!
