The Sun says the city does not have the hard economic numbers/estimates for this long baseball themed weekend, but even if they did I doubt they would share them alongside the Grand Prix numbers. Around 100,000 people will walk through the turnstiles at Oriole Park this long weekend. Bars were PACKED on Friday night and they should be crowded again on Sunday and Monday nights. Everywhere I go people are in great moods, and when people are happy and drunk they tend to spend money.
The Orioles winning ways have generated a positive economic impact for Baltimore. I am not a Grand Prix hater, but I think it says a lot about projects like the Grand Prix when an already established entity easily outperforms it economically. The city already has some potential goldmines. Instead of trying to come up with new events with large start-up costs we should make the most of some of the hidden gems we already have (for example: the city has yet to harness the full economic potential of the Preakness).
