The Park Theater very quietly celebrated its one-year birthday on Monday. This was somewhat disappointing because I was pushing for a rowdy celebration with ice cream and punch.The Park Theater's first year of returning to an entertainment venue has been rich with flavor -- sort of like cream cheese icing slathered on top of a giant cookie.The main setback would have to be the inability to show movies. The city had hoped for it to be a place for second-run movies and even had a retractable screen installed during renovation.
