Does anyone have any inkling as to why there have been those ugly white tarps underneath the METLIFE signage on the top of the stadium? They have been there for almost a year, if not more and the only reason I could have deduced was during the winter, the fear of snow/ice buildup on the top of the letters falling down onto escalator riders. Regardless, they're hideous and I need to know what they're real reason for existing is!

(I work in that big white office building across Rt 3 so I must look at this debacle on a daily basis)
