My favorite, although it was taken with an antique digital camera so it's not as clear. It was taken at the point where the Potomac and the Shenandoah Rivers meet in Harpers Ferry, WV. At the time Roy took it, I was set up at Antietam Battlefield and had nearly as beautiful a view.
And this one came in from Connecticut last year.
And although GPS now lets crews get in and out much faster, once upon a time you just kept on going, as this pic from 1916 Alaska shows. The crew are measuring a distance with invar tape.
