Think you're a sports nut? You're probably out of your league.

In preparation for the big game, California football fan David Spiller has created what may be the ultimate Super Bowl man cave, decking out nearly every inch of his guest house with NFL memorabilia, and even installing a snow machine to simulate potentially bad weather conditions.

Spiller's "super bowl central" is replete with countless jerseys, helmets, pennants, not to mention 13 televisions-including one in the bathroom-to ensure viewers never miss a play.

Spiller's snow machine is just in case of inclement weather at this year's Super Bowl, the first to take place in a cold-weather, open-air stadium.

"I always say, 'enter at your own risk'" he told ABC News station KABC-TV.

Worried about watching the half time show? A fog machine and 70 laser lights will help viewers feel like they are actually at the game during the performance.

Spiller, a musician and retired contractor, says he picks up much of the NFL memorabilia adorning his Super Bowl cave from thrift shops, and gets many of the items for free as promotional items from local stores.

Spiller acknowledges his elaborate man cave may seem a bit much, but for him, love of football comes first.

"It's for the love of the game and it's just a fun thing to do," Spiller told KABC.
