Adobe Mountain Speedway (AMS) has recently reopened the dirt track area south of the PKRA track. For up-to-date status, see their web site at https://www.adobemountainspeedway.com.
A great deal of work has been done to revitalize the site, including new electrical, new catch fences, site cleanup, and other improvements.
While PKRA will have overall responsibility for both sites, AMS will be operated independently, and all questions should be directed to their contact page https://www.adobemountainspeedway.com/contact-us.
