You're really missing out! In my opinion, PBR is the best of the "cheap and shitty" tier of mass-produced beer that rednecks and poor college students drink to get smashed. It's not good, exactly, but somehow nostalgic to me for drinking around a campfire. The U.S. has plenty of mass-produced beer that's still mediocre, but better than PBR, and some that's even pretty decent. It's in the craft breweries that you'll find the really great American beer, though.
