The location of this gala event is Home Valley Park along the mighty Columbia River just outside Carson, Washington. Please introduce yourself to me. I'll be in the beer garden at 5p.m. and camping at the nearby park with Bob and Patti Reinhold by the railroad tracks. FYI, Skamania County, Washington is one of the hottest counties in the nation for sightings of 'Mr. Saskey'.
That said, if you want to camp in a sqautchy spot near the venue on either Friday or Saturday night, find the USFS Cougar Creek Campground about eight miles up the Wind River. It is nearby and very squatchy.
