The Lowell Lock Monsters are the American Hockey League affiliate of the NHL's Carolina Hurricanes and Colorado Avalanche. These are players one level below the NHL and they're working hard to earn their spots, so this is some excellent hockey. They play in the beautiful Tsongas Arena in downtown Lowell. The best seats in the house are only $18 ($10 for children 12 and under). Compared to going to Boston, it's a real bargain. Louie the Lock Monster is a kids' favorite. Overall, a great, affordable night for the whole family. One note of caution, the arena seats are pretty tight for big fellas.
