To burn of  the burger for lunch we took a bus ride to the base of the Golden Gate Bridge and walked the mile or so across.  It’s not anywhere as big as the Bay Bridge on the other side of the city but is just as impressive. The bridge is a fair way out of the city centre. The views were spectacular and the 3 foot high barriers were all that stopped you from ending up in the drink below, other than the signs saying it wasn’t a good idea to jump.  At Alcatraz the other day they made a big hoo har about how dangerous the currents were, we thought it was just adding to the legend they had cleverly crafted but from up on the bridge you can see them and they were amazingly strong.
