In San Diego, it cost $10.00 to go into the AC Village area, but you can get really close to the boats and watch the teams rig and launch. They also had a big screen TV that was showing the races as they were taken place.
The Rigging, hoisting and attachment of the Wing was very interesting to watch......link below goes to an album of photos that I had taken at San Diego.
