In handwritten note to Brett Gustafson, Project Manager for GeoStabilization: “Brett – Thank you for your quick response to reopen Blue Slide Road in Sanders County. Your talented team was available to complete a road for the public to travel on in less than 45 days. Mother Nature has challenged us in Montana this year with moisture in all forms, and we appreciate your resilience in the face of those challenges. Sincerely, Steve Bullock.
