Check out KC Stadium in Hull, UK. It was built for $69 million in 2002. It holds 25,400 seats. A roof protects the fans from the weather and has no obstructed views. Something like this stadium would be just perfect for Halifax. The stadium is not over the top, yet provides more than just a bare box. This style of stadium can be used for sporting events as well as concerts.
