The blow to collective dignity may well be a bigger loss than the 2,000,000. The message is something like your small town can be the next Tijuana. So now arrive the losers (alcoholic frat wannabes ) and the parasites (liquor companies and other purveyors of vice). A lot of them will stay, bringing both cash and fucked up behavior, and the town may drift toward being a place that caters toward the worst of humanity (yuck). Some folks will be happy for that, seeing the money, but some of us are disgusted, seeing the degradation on all sides, whether selling or buying. No, I don't like Bourbon Street or Indian Casinos either, no matter how much money gets made.
Where's this $2m coming from? The article says the company are paying ("donating") $500,000 and that drinks will be unlimited - which presumably means provided by the company?
Will the 1000 party goers spend $1.5m? $1500 each at a 3 day party where you're not paying for drink sounds really high.
Likely from all the preparations, and hiring the local restaurants/bars/etc on the main drag. Who is going to clean up all the blue paint and throwup? Local guys I guess.
Hotels, food, drink and other necessities for the 1000 party-goers, plus hiring local staff to run the event. Bud light is not really going to support you for three days straight.
