That's good. But hold on to your plumage. Today I think we've spotted what certainly must be a heretofore unknown species of pelican. I think we should call it the American White-Water Pelican, as we've only seen it near river rapids. In fact, we have observed some of these birds get to be really big. Could this be one of the largest birds in North America -- maybe the world? I've added two numbers to the top of the blog. They are the great circle distances from our start point on the beach in Pacific City, and the remaining distance to Atlantic City (to Tennessee Avenue, to be precise). Is the Greater Pittsburgh still there? These are great circle, so called "as the crow flies" distances based on the spherical law of cosines (not the haversine formula). It's interesting to note that today we are 1301 miles from Pacific City, but my bike computer says I've ridden 1876 miles. So our zigging and zagging has cost us about a 44% distance overhead relative to the shortest path on a spherical earth.
