If you're going to stay it pays to get here early in the week. There's a bazillion truckers here. The parking is supervised so if the lots are full, you wait in the street until a spot opens. Then a guide car takes you back. Shuttle busses run from the outlying lots to the venue on a regular basis. A lot of folks are renting cars too.
We haven't had any trouble booking an Uber to get to and from downtown for dinner in the evening. Plenty of on-site entertainment too.
The Uber tent just happens to be close to where some of the guys are parked. There is plenty of other entertainment sponsored by other outfits too.
