I grew up near Cheddar, If you were expecting an Empire of Cheese it's surprisingly modest. I recommend Wookey Hole and the area is a good place for bike rides (just not on the weekend). I seriously recommend Thatchers Gold [cider], that's probably Somerset's best export (and the Wurzels if you like cliches, only builders and farmers actually sound like that).

I thought cheddar took off because it's easy to transport and store).[/success kid]

PS: Cheddar is definitely nicer than creme fraiche (unless you enjoy soggy sandwiches, and a salad... no, just no). ;)
