Reader’s Quiz: What’s Happening Here?

Let’s have some fun.
A YJI student (who shall remain nameless for now) sent in this photo and some others (from a place that shall remain a mystery for now). The student also sent a bit of writing about what’s happening here. I’m waiting to hear back on a few details, so until then, I’m posting this photo with a challenge to see if readers can guess where it was taken and what’s going on.
Please check back later to see the rest of the pictures and a full explanation, but meanwhile, post your guesses as comments below.
