The Bucking S Ranch has been sold as of June 2014. It is no longer in operation as a guest ranch. The new owner will use the ranch privately and the cabins are not for rent any more either. If you are looking for a ranch stay you can refer to the Wyoming Dude Ranchers Association or the national Dude Ranchers Association. They offer a wide variety of ranch stays including working cattle ranches.
Dan and Silke are no longer involved in the guest business and are enjoying life on a hay farm in Wyoming. If you like to contact them personally, you can still reach them under their old emails or find Dan on Facebook.
