Accommodations

Since it's a two-day event, we expect you'd like some place to stay at night.
You may stay at the track for the duration — there's room for camping trailers and tents. There are no sanitary hookups, however. power, water, and restrooms are available.  
Camping is free, no official security is provided.

Note: Under no circumstances are vehicles allowed on the racing track after the event hours!
Doing so will result in your ejection from the event.
