Rainbow walkway

The locals support it: It is good for local businesses by bringing additional tourist dollars and creates community goodwill following an ugly incident at Mardi Gras. The costs were for painting the road and then repainting the road. There is real coverage of "paint over the rainbow!" because outside the one or two people in the government, no one has this position.

And yeah, the major expense at this point, if you are wanting to save money, would be to paint it over. Suggesting you want the rainbow to go for monetary reasons is counterproductive because of that.
