My wife and I took our kids to the game last night and after receiving our beanies, my wife noticed she had a piece of paper in hers. She ripped it out to throw away (thinking it was some tag or 10% off coupon) when I noticed neither I, my son or my daughter had one so I grabbed it from her. "It said Congratulations!! You are a winner of the Hidden Halo." So we took it over to guest relations and received an autographed HK47 baseball and some other goodies. The guy said they are going to do this at every promo night and will be giving away between 5 and 15 things each time. What an Awesome promotion!
