Ugh. I feel like I just paid $7 (admission fee with coupon) to watch a bunch of infomercials. You walk in and it's just a bunch of booths selling spas and blinds and phones and non-working health devices. I saw nothing "cultural" or "religious". The food was way overpriced for what it was. If you have no means of getting out of the city, then this might be the place for you; I have experienced festivals waay better than this one.
Even though parking is free and everyone wants a close parking spot (who doesn't?), you're better off parking in the Bass Pro Shop parking lot and walking either through the store or around the Bass Pro Shop and to the front of the Silverton. You'll save yourself a lot of time and hassle and the police directing traffic. If you take that main turn to the Silverton, you're going to be stuck for a while with everyone else going to the Festival. Keep going straight and around the corner and you'll see a place where you can turn left to the Bass Pro Shop parking area.
Oh, and don't forget to bring CASH. Don't get stuck pulling out money at the ATMs they set up front.
