It's NY-Penn, so I think you'd try to find a place up there. If RobRyan is sitll around - isn't there an old Superfund site in Burlington, maybe a ship canal? Do they have much of a brownfields program for reuisng contmainated inustrial sites? It sounds weird, but ball parks are a great reuse of these sites because they are not residential and can cap drainage. Lowell's park is built over an old ash dump.
My apartment is downtown by the old sailing center. They just posted public meeting notices about re-developing that land for a new skate park, and other lake front beautifications. This is really the only spot I could see a ball park fitting, and clearly the use for that is not there.
The owner of the Monsters own Lake Champlain Ferries... he has money. That's where the rub comes from him asking for money for a park to be built. I COMPLETELY understand him not wanting to pay to fix UVMs property (Centennial), but I also get the city and state saying "umm, no," for him to build something.
NOW, there is an "X Factor" in all of this, and that's Centennial Field's age. It's a historical landmark. Through the historical committees they're trying to get some of the funding for upgrades, or at least block plans for doing something ELSE other than a baseball field (a hot rumor is UVM building student housing on the grounds.)
