About 22,000-26,000 of the people at the Big Chill were students who paid $5 (w/season tickets to hockey or football) or $10 (bought by itself).
Unless you want to actually sell tickets for $5, you invite Toronto. Toronto fans are the dumb ones in Western Ontario who follow the Leafs and will drive 2-4 hours and pay $20 or $30 for ****ty seats especially given their pricing in the ACC. Boston fans will sit at home and watch on TV, especially since they have outdoor hockey of some variety almost yearly at Fenway.
