Where in Berkeley?

Know where this is? Take a guess and let us know in the Comments.

Update, 9:11 am: Reader “Completely Serious” got this fairly tough one pretty quickly. The target is part of a makeshift play area up in Tilden near Grizzly Peak Blvd. Congratulations, Completely Serious (who is clearly not averse to being a little unserious sometimes) on being this week’s winner!
