This coming weekend at KC Kansas. Take I 435 north. Just north of the Kansas Speepway about 1 mile,exit right on Leavenworth road, then go east about 1 mile to the Woodlands horse & dog track then you will see it. Happy hunting. 9700 Leavenworth road.
Depends on what you might consider big. I've seen it as many as 500 venders & as small as 200. I've also seen it where they did't have any spaces left. You never know this time of the year as to how many venders will set up. Anyway I've been going for the last 8 years & I've not been disappointed.
