Where in Union? {June 15}

Where in Union is this stone? If you know and are the first one to correctly comment on this blog post or the Facebook post, you will win a pizza from Philly's!

Please comment with the exact location, including street/streets, buildings, any identifying landmarks, and even GPS coordinates. The first correct comment wins the pizza. You may comment on this blog post or on the Facebook picture.

Also note that I love a very thick crust with chicken, black olives, and extra cheese. I don't mind some marinara dipping sauce, either. ;) Sorry, no hint for this week!
