Give 'em a photo of you and/or your buddies enjoying the great outdoors with a Sierra Nevada can, and they'll throw a t-shirt in the mail for you. It's that simple. http://www.palealecan.com/home.html I'm not about to rush out and buy a $50 case of Torpedo (got enough to drink here already), but seems like a decent enough offer for anyone who's already got their hands on the good stuff.
WTH, did they change the rules? I could have sworn that it said earlier that all you had to do was send them a picture and you get the shirt. So I go out and buy some SN Pale Ale and now it says; Starting on April 6, 2012 11:59pm PST (Pacific Standard Time) through May 31, 2012 11:59 PST (Pacific Standard Time), all submissions will be entered for a chance to win a free t-shirt, while supplies last. LAME!
