I can't believe I've done 18 of these. Even more impressive is I've only skipped one week. Unfortunatly, I realized last week I'm just not up to posting hints and remembering to check back occasionally so I've decided I'm going to change the plan. Same rules for the photo, it's taken somewhere in the 7 county metro area. I'm no longer going to post hints, and will post the answer in the comments on the following Where?.
BTW last weeks photo was taken outside the armory on the U of M campus.
Here is this weeks photo.
This shouldn't be too tough if you keep your eyes open. Though I realized I had driven by it many times before I noticed it.
