From Lemonade51o: A is for Alameda! This design encompasses the Alameda Portal/Posey tube on Webster Street and the infamous Watermelon Rock (located on the rocks of the Martin Luther King Regional Shoreline Park) which is graffitied on the side in this design. The watermelon is also a double entendre for the Watermelon Symbol that represents a Free Palestine. :) Fun Fact: The Alameda Portal was designed in 1928 and the Posey Tube is the second-oldest underwater vehicular tunnel in the United States!
