Actually, I'm not sure about that math... 50,000 * 30 games = 1.5M people per year. Let's say regulars/repeats/tourists are 3/4 of the people - 300K new local visitors. A lifetime is (say) ~80 years. In a lifetime, (7.7/8)^80 = 4.6% chance you don't go to YS at least once in your lifetime. If I had to guess, MSG is better than YS because it hosts a wider variety of events and it's in the center of town with easy transit access, i.e. more new local visitors per year. The better analogy might be a venue like Forest Hills, which is far from the city. Take Grand Central Station - certainly, most NYers visit once in their lives...
