The Walmart rumor is still just that, a rumor. It's popped up a time or two over the last couple of years. Someone on another forum said someone close to the track said that it is expected to run at least next year. A few other rumors around as well. Carl seems to be keeping the details a secret, probably out of necessity. I think it's one of those things we'll know for sure when there's an "official" announcement from someone involved with the track property now or in the future.
