(St. Paul, MN)  —  A Minnesota park is cutting back on its Christmas decorations this year due to wire-munching squirrels.  Officials in charge of the display say vendors refused to hang string lights in the St. Paul park this year citing squirrel damage from previous years.  The wires are reportedly coated with a polylactic acid, a corn syrup derivative that squirrels apparently love the taste of.  This year’s display will opt out of string lights and instead have projected images of snowflakes along with lights at the base of trees.
