1,400 breweries in England vs. 6,300 in the U.S. If you didn't find a beer to your liking you should have keep looking.
By my maths that makes 1 brewery every 93 km2 in England versus 1 brewery every 1561 km2 in the USA.......that's a LOT of looking. There is the perpetual problem of finding decent beer in the US and it's not helped by the lack of breweries per km2
