We haven't been in a few years, but we went the Sunday, which was the day before we went to Pigeon Forge Tennessee. We went about as soon as it started on that Sunday, and it wasn't crowded too bad.
We passed around the vendor tents first. They always have some neat stuff. We never get any of it to take home usually, but I do like seeing some clever/cute stuff.
Kids have their own kiddie rides and while my Little Brother Mr. B and my niece Little K were there, they didn't ride those.
Before we left, it did start to get crowded, Which made me glad I didn't go on a Saturday.
