The Foxer

Warm-up Foxer (Where am I?)
I'm at the junction of three roads, all of which are named after rivers. I can see an airship. If I walked north ten paces I'd end up on a railway line. The country I'm in has a female head of government and has qualified for the FIFA World Cup twice. I'm in an oceanic climate zone. Mesopotamia is 100 miles away. The town I'm in has something in common with a Manic Miner level. A famous PC game designer grew up here.
