Springfield is a city in Massachusetts, United States. It sits on the bank of the Connecticut River, just a few miles north of the border between Massachusetts and Connecticut. Along the river, the city is fairly low and flat. Moving outward from the river, the terrain becomes hillier, most prominently along State Street and Belmont Avenue. Springfield is part of a resort area whose primary attractions are the largest cave in North America, an outdoor exotic animal park, and Bass Pro Shops Outdoor World, one of the most visited tourist attraction in the state. Springfield has been home to a number of minor league baseball franchises, the last club leaving the city after 2001. Today, the city is host to the Springfield Junior Blues, a minor league hockey team, and the Springfield Stallions, an indoor football team who played at the Prairie Capital Convention Centre in 2007, though the team failed to complete the season due to financial difficulties.
