A quick driveby visit. An Auroran "Must See!". I don't know the story behind this one, but, its been there for years. It keeps changing and growing.

To Qualify: Post a photo of your favorite concrete item, include atleast your GPS in the photo. A "drive-by" photo is good enough.
This is a private residence, so stay on public property. Do not make a spectacle of yourself (or Dr. Smith). Definitely visit in the daylight hours. The Aurora area can be a little rough, be wary.
