What exactly is a mixed-use community?
If the MSG powers that be are freaked out about losing future U2 concerts and Republican National Conventions, they need not be. Box lacrosse, indoor soccer, arena football, rodeo, expanding the Westchester County Dog Show to include cats, etc. are all intiatives that will keep the World’s Most Famous Arena humming with activity year round.
Failing that, perhaps someone can start an ice-hockey league.
