Agreed.
The ideal setup for the university is to play all the home games at the same venue, and offer STH the chance to buy season tickets for the venue for all home games. That gives them more cash flow and a degree of continuity that will help retain STH during a difficult time. Cornell would be easier and the size would be adequate but as others have noted, they also play on Saturdays and they also have a football team and they have their games on a college campus...finding 6 or 7 open Saturdays there is very unlikely and it probably isn't worth it to only play one or two games there.
Last time, using three venues for 5 games made this impossible. I was a student then, don't think they even offered us the equivalent of a season ticket that year.
Anyway, if we lose a year of home games at the Dome, I support moving all the games to Ralph Wilson. It is a relatively easy drive, the tailgating would be excellent, it would be easy for out of towners to fly into and I think we would be able to play all the home games there.
