The naysayers are already at it in the local newspapers saying a new arena is all a waste of money. Why, because it might not make a profit. If we follow that thread a little more, here are other things that don't make a profit for cities. Libraries, senior citizen centers, parks, community centers, summer day camps, after school activities......well, you can see where we would be if all we concerned ourselves with was what made a profit.
I am not sure any arena can make a profit, although the Isotopes park is certainly doing so. Maybe the best we can hope for in an arena is a small subsidy or break even situation. If we are going to be all that this city should be then we need a multi purpose arena for everything from music events to indoor football games. This is the kind of thing that great cities do. We did it once before in 1957 when Albuquerque opened its Civic Auditorium. It was torn down 30 years later and it is time to build a new one.
