Wow, the "internet" of its time,
before the Civil War! The Transatlantic Cable. What a great development in communications. Great pics, thank-you for the viewings. It was
after that when we laid the "Gold Spike" into the North American Transcontinental Railroad, at Promontory Point UT (1869).

For those of you who are into such things, our tapping of undersea cable to detect messages during the Cold War, using our submarine fleet and certain "independent contractors," (the Hughes Corporation's Glomar Explorer, to salvage a Russian nuclear sub that was wrecked on the bottom of the ocean) makes very interesting reading.

The second link contains the story of the newest USN nuclear attack submarine
Thresher, which was lost at sea April 9, 1963. I was a kid vacationing in FL during spring break from NY when that happened, and I recall reading about it in the newspaper, the nightly news broadcast on TV, and wondering like everyone-else, "what happened?"
When you travel, you never know what historical sites you may encounter. That's why you want to take your time and to be on secondary roads. Yes, travel takes longer, but the serendipitous events you have are why you're traveling in the first place.
A trip I would like to take is from the start of US 27 just off Biscayne Bay in Miami FL to the top of the lower peninsula on MI, which I believe is its conclusion. Then I'll have my own photos to recall the fun of the trip, like these guys who've had such fun in the journey and the experiences.
"Good on-ya!"
