Light display showcases Minnesota couple's Vikings pride

It's hard to ignore Joe and Michelle Cairl's house--especially if you're a Vikings fan. 

Outfitted with music and plenty of purple lights, the Andover firefighter and his wife conceived, designed and built the display--all with a little help from his brothers and sisters at the station. 

The couple plans to keep their music and lights up through the weekend and--if the Vikings win--until the Super Bowl.
