|Halfway to the tide line. That's Point Roberts and Centennial Beach at the far right.|
|Walking the dog, far away. I think this is directly south, near the edge of Semiahmoo Bay.|
I walked to the west edge of the beach, but then there was a wide stretch of water before the sand started on the Centennial Beach side. Of course there was; there's a river running down through there, the combined Nicomekl and Serpentine Rivers flowing out of Mud Bay.
And it's 7 miles, shore to shore. It just looks like a quick walk.
