Two year's ago the America's Cup was contested in San Francisco. It was a wonderful venue. Access and viewing were ideal. I was in San Francisco to speak at a conference and had a couple of opportunities to watch the boats run. It is truly amazing. A lot of the venue was open to the public, only a small area was limited to those willing and able to pay.
The boats are very high tech, sailors of 100 years ago, would be baffled by the carbon fiber masterpieces of engineering. The boats are amazingly fast and agile. This was a wonderful opportunity to see them in action.
