Greenwood Avenue Bridge
Posted February 2, 2010, by Matthew Martel (myrtle91 [at] gmail [dot] com)

I visited Calistoga in October of 2008. My wife and I eloped at HANS FAHDEN. We stayed at Dr. Wilkensons on the Calistoga strip. We went site seeing and came across the Greenwood Ave. Bridge. My wife loves historical sites so we stopped and checked it out. We will never forget this bridge because right at the bridge is a tree, a walnut tree. We had no idea that walnuts grew in a green skined fruit looking shell. We thought they were limes till I found several walnuts on the ground and decided to open one. The bridge is tucked away down a beautiful street where the veiw in breath taking.
