Yuengling is fine for what it is. Not great beer, but a small step up from Bud -- at least the Black and Tan is. And they haven't been bought by InBev or whoever (as far as I've heard), unlike Rolling Rock or Pabst.
I sometimes go for a Rheingold, another old timey beer that was revived for the ironic hipsters. But Rheingold probably isn't any better than your average p*$$ beer. For whatever reason, they're available in New London, Middlesex Fairfield and Hartford counties only. I saw, but didn't buy a Gennesee at the store... not the cream ale, another one. And I haven't tried a Ballantine's either yet but eventually those will be in the fridge... next to the Ommegang Hennepin farmhouse style Saison.
