Rolling Rock was a better beer before Anheuser-Busch took over the brand. They shut down the original brewery in Latrobe, PA. I have no idea where they brew it now but it isn't the same. Different water could be the culprit. Never was a great beer but it wasn't bad either.

What I do know is Rolling Rock was never a good choice if you were planning on getting hammered. The hangovers were terrible.
