This morning while watching out the window, I thought I could make out a figure sitting by the puddle. There seemed to be a face with what appeared to be green stripes or some such design on it. I quickly opened the door to have a better look, and just as I did, the thing leaped back into the puddle. It happened so quickly, I was now questioning whether or not I'd seen anything to begin with. Yet, the water was obviously disturbed. I cautiously approached the puddle and peered as far into the water as I could.
At first I saw nothing. I concluded that the creature must be able to hide within the valve structure. Sure enough, I eventually made out SOMETHING between the segments of the anti-siphon valve. I could swear I saw zig-zaggy designs on what looked like a spiny back! But the water gets murky that far down and I couldn't make out any designs beyond that.
I am thinking about a installing a live web cam so the puddle can be viewed at all times from anywhere in the world in hopes of capturing some footage of this elusive creature.
I'm starting to wonder just how extensive this irrigation system really is. There could be multiple segments going for several feet -- perhaps even extending into neighboring irrigation systems.
