Know where this is? Win a t-shirt ~

OK, Tucson experts ~ it's time again for the "Where is it?" contest! Here's this month's fun architecture challenge. Post your guess on where this building is located and/or its name. If you aren't a site follower, that's OK, just use the "name" selection in the comment box. Whoever posts the correct answer first wins a "Bad Day/Monday Already?" t-shirt (see posting on Feb 16). Good luck! P.S. Since you won last month's contest Ellen I'm asking you to sit on your hands!!!  (:
