If you're not familiar with UK geography, here are some maps to give you a little context. I couldn't find an inn called the Crawfordsborn Inn, but The Old Inn sounded close, and was an appropriate distance to walk to from the Bangor Marina (I approximated it 2.4-3.0 miles each direction). Hopefully I'll be able to come back later with Photoshop and touch-up these puppies.
