HINT provided for "Where is this?"

OK Tucson lovers, it's that time again for another "Where is this?" contest! So here we have some of Arizona's icons: a road runner, a mountain lion, an eagle, cacti, and fantastic rock formations.... where is this mural? As you regular site visitors know, the first person to correctly identify this location wins a "fabulous" TDP t-shirt or mousepad featuring our expressive ram wondering, "Monday already?" Good luck!

Wow - no guesses yesterday! OK - this mural is NOT at a museum as any kind of diorama. This is a very public place - no admission fee. It's south of River and north of 22nd Street.
