The driving directions will tell you that you need to turn on Dussel Drive. That solution works but you can actualy just make a U turn there and turn right into the parking lot a little after the Speedway Gas Station. The Soccer Center should be visable ahead on your left.
Below is a map of the festival location. The Soccer Center is at the top of that grey area just left of the top of the bubble with the A.
If you click the map it should give you the option of getting driving directions.
