Art in Spokane may soon get some new patrons: film junkies, Zags fans and concertgoers. Under a proposal by City Council President Ben Stuckart, arts funding would jump from $80,000 to about $250,000 a year. The funding would come from the city’s admissions tax, an existing charge on every ticket sold to enter a venue or attend an event, including movies, sporting events, concerts and art shows. A third of the tax taken in by the city would go to arts funding.
