Is the Super Bowl being played on grass on turf?

I swear I can't get a real answer from anyone, conflicting stories all over the net.

Anyone know for sure?

First it was turf then it was real grass being brought for the super bowl now I hear turf again.

:wacko:

its specially made from Jerrys pubic hair. He has been saving his clippings since he was 19 for just such an occasion

They have storage units full of it.
