The Sandhills Open Road Challenge is unique in Open Road Racing events. It is a 52 mile race held on twisty, narrow farm roads out of Arnold, NE. I have always wanted to try it because our ORR Camaro is really set up to handle. Speeds in this event are MUCH lower due to the twisty, narrow, rough road. This video is from Mike Border's Cup car that set the course record of 133mph on the first leg.
The race is held the first part of August each year and entries typically close in October! I was lucky enough to get a slot for '07.
