We all know that $10,000 is the tip of the iceberg. I bet if you dug real hard you could eventually come up with the real cost. As for your calculations as to how much this elusive tourist would have to spend to vindicate the mayor, I suggest you are way too low. You assume a dollar-for-dollar direct benefit to the city. Not so. While it is nice—even essential—to have tourists here, and they do add substantial dollars and employment to local merchants and businesses, and there is a multiplier effect to the money they spend, the city only benefits directly from the tax revenue generated.

You get the point. We’ll never see a payback in this century.
