The founders of a local group that envisions establishing a modern 600-seat performing arts center in the Gorge will hold a town hall-style event this weekend to outline their idea.  Mark Steighner is President of the Performing Arts Initiative, and he says a feasibility study is being done to determine what is possible.  He adds the vision includes a facility that can be used for a wide variety of purposes, noting current facilities in the region are limited in many ways.  Steighner says the group has explored several different potential locations in the Gorge, but are not to the point of selecting one.  The Performing Arts Initiative will roll out their idea to the public Sunday evening at 7:30 at Naked Winery in Hood River.
