Wow.

Any info? I’d like to read the history of it.

Desert View Watchtower - Wikipedia

In 2008, two tourists were banned from all American national parks for the period of a year after using white-out and permanent marker to correct the punctuation on a sign on the Desert View Watchtower, which had been painted by Colter.

The fact that they had whiteout and a sharpie on a trip to the Grand Canyon tells you a lot. Anyone enraged by improper punctuation would understand.

Just for you… youre welcome.
