from where I sit , it seemed that there were a lot of people who had bought tickets and or booked accomodation who WERE there for the festival - Several reports about Sold Out concerts - but the fair number who seem to come down 'on spec' and find a campsite out of town , then see where they wanted to spend their time , were put off by the weather forecasts as were a lot of the Day Trippers . Made more sense to save their pennies , stay dry , and watch the Olympics
