Recycle the grime! Maybe RCAF can make and sell little bottles of the upper deck grime with a pebbles of crushed concrete and sell as 'old' Cajun Field memorabilia. We can proudly hang 'old' Cajun Field grime bottles on our rear view mirror or tailgate tents. I'm being factitious, however there will be some nostalgia about the upper deck in some corners after it comes down.
