We stayed, long term in 2003/2004 in our 27 ft Sunnybrook TT - eight months while our house was being built - at LeMar Acres, a trailer court in Yelm next to the Safeway. They are in the process of selling the place now and are having people move out. Depending on your status and how long you need a spot, you may be able to work something out with the owners if you can locate them. A place to start looking is Jim Bob's Restaurant in McKenna, next to the Chevrolet dealership, family members of the original owners of LeMar Acres run Jim Bobs.
