I especially like the stars denoting danger. I don’t know what made the railroads and trolleys so cross, but it would be best to avoid them.
Not quite as good as the old-school “street view,” but early automotive guides provided scenic touring descriptions, with turn-by-turn directions, for those adventurous early motorists. 61.2 miles sounds like a day-long adventure in an open-topped flivver from 1916, when this route was published in the Scarborough’s guide. With some variations, this is still a route I might bicycle today, though I’m betting that as bad as the pavement is here in the 21st century, it’s got to be more even than it was back then.
