Lots of great things going on in the photo above (larger version below the fold). First, this guy at this weekend's 5K Mud Run at the San Joaquin River is sporting a great Hulk costume. Second, he's telling everyone to send a message to their leaders in support of the San Joaquin River restoration (Send your email). And last, he's making a big pitch for the Yellow Warbler for Audubon California's Bird of the Year (Vote now).

Look at all these people enjoying the River!
