Flat

The fens are flat. Very flat. There's lots of sky here. So much in fact that USAF love exercising their aircraft in it. According to the RAF Lakenheath Commander it's for 'combat readiness in Iraq'.

What's wrong with Iraq's sky? Isn't it big enough?

The fens are also weird. Populated by weird folk driving tractors. I really miss big towns and ordinary sociopaths!
