When it’s too cold to go ice skating, that’s cold.  Officials at the Titletown entertainment district in Green Bay have announced tubing, ice skating and the 46 Below Bistro are closed until Thursday — even though it’s nowhere close to 46 below.  Dangerous wind chills led to an advisory which resulted in the closure, just a few days aftr tubing on Ariens Hill had opened to the public.  Officials say Titletown will be open recreation facilities Thursday at 10:00 a-m.
