If you've walked along Fourth Avenue or been to one of the festivals there, you've probably seen the mural “Together We Thrive” that wraps around Winsett Park, 316 N. 4th.
The Tucson Arts Brigade is restoring the mural. If you're between 13 and 17 and you want to help, they meet each Tuesday between 3 and 5 PM at Howenstine Magnet High School, 555 South Tucson Blvd. There's more info on the Tucson Arts Brigade website murals page; though it (currently) says the project will finish in April, Michael Schwartz (TAB's Executive Director) told me that the target date is now June 15th. If you'd like, you can bring a mentor up to age 22 or so.
I stopped by the park on October 4, 2011 — before restoration started — and found the gates were open. (The park is often closed when there isn't an event going on.) I snapped a series of photos in a semicircle from the rear wall southeast, to the beans and seeds under the west end of the back wall, to the west end of the north wall, to the right (east) end of the north wall:
two parts of the mural (above), as well as a photo of the stage (which isn't shown above).
