The RV power poles will run your tire warmers, we rented them last year for $35/day $60/weekend. Here is the HPR website RV power spot rental info...

..the power poles themselves are deep into the gravel parking spot for the RVs, I recommend you bring a long 3-plug extension cord so you can reach your bike and warmers out on the asphalt pit lane.

The Longhorn Motel in Byers is older but clean and neat, and less than 15 minutes from the track. They only charge $50something a nite, their phone number is 303-822-5205. They're located right next to the Byers General Store, a nice small grocery with good selection of food drinks and ice for coolers.

See you at the track!
