Like a sentinel...

 

Presiding over the streaming traffic and making sure everything was on the up and up. I imagined, in case of emergency, guns would pop out of the holes that went around this fortress and start flat-blasting anything that moved. So, I approached cautiously, tripod in hand and held over my head, so they could see that it wasn't a weapon and that I advanced towards them in peace. "Ha! Ha! Stoopid me!" I had to laugh aloud. It was only a water tower.
