T & I used to go to festivals, not music festivals but orienteering festivals. In 1983 our then 'club' was responsible for the car parking of an annual international event called the JK or Jan Kjellstrom http://www.jk2010.co.uk. Around 4,000 runners attend this most years. Here is a little yellow VW at the start of the day.
As a student I also use to drive one of these (below)for the university team. BUSF stands for British Universities Sports Federation. They had an annual event too.
That's me! And T peeking out of the back.
