Yuengling is a good, easy to drink, domestic lager, pre-prohibition style. It’s not perfect, but it is easily the best cheap beer.
There are tons of amazing breweries literally everywhere. I don’t have a favorite beer, but I do have favorite breweries. Ales and IPA’s are generally my bag, though Flying Dog’s Gonzo Imperial Porter is totally badass.
Try Bridgeport, Flying Dog, Big Sky, or Saranac for adventures in American beer. For a more Canadian experience, try to track down a case of Alexander Keith’s or Rickard’s.
