Packers President and C-E-O Mark Murphy took the first trip down the new sledding hill in the Titletown District Thursday.  Tube riders can speed downhill on the 300-foot thrill ride after the grand opening.  The hill was designed to focus on giving a typical 13-year-old an exciting ride.  Introductory pricing costs three-dollars-a-ride, tube rental included.  A rider has to be at least four years old and 42 inches tall.
