Golden Gate Park is a tourist 'No Shit Sherlock' destination. But the Dutch windmill is where you want to end up. Some great picture spots at the Tulip Gardens and across the highway from Ocean Beach
In 1921, Velma Tilden rode the rotating blades of the Dutch Windmill for 25 turns as a publicity stunt. http://oceanbeachbulletin.com/2011/02/08/before-now-riding-golden-gate-parks-dutch-windmill/
