Mystery Photo: Sprinkler Alarm [CLUE ADDED]

Update Monday, Aug. 13: Since no once guessed the origin of last week's Mystery Photo, we'll run it for one more week, but this time, with a clue: pull this, and you'll clear out the swimming pool. 

Each week on Melrose Patch we feature a photo taken somewhere in the city. You, our readers, have until Friday to guess its origin.

Think you know where this photo is in the city? Submit your guesses in the comments section below. Only guesses left there, and not on our Facebook page, will be counted. (Remember that our Terms of Use do not allow aliases. Also, we suggest that you use your full name for your Melrose Patch account. You may also  in using your Facebook account.)

Each reader is limited to one guess each—and if you've guessed correctly within the past month, please hold off and allow others a .

If no one has guessed the location after a week, we'll re-run the photo the following Monday with a clue. The first reader who guesses the location correctly will win bragging rights and a Patch canvas tote bag.

Good luck!
