We went to the Empire State Building late at night (maybe 11 or 11:30). We walked down after we saw Jersey Boys. It was perfect because there were no lines....but you could see all the ropes for the queues, and they went on forever!!
Stopping at the overlooks on both sides of the bridge is always fun and awe-inspiring! Then, drop down to Sausalito for a nice lunch on the Bay, gelato afterwards, and then onwards with the road trip...
