Cowley Rd Carnival Mini

In South Parks this weekend, the residents of Oxford where having a carnival, The Cowley Road Carnival. Mini is one of the main sponsors, and had one of there new models badged up at the main entry to South Parks. The carnival is very popular, and there was loads to do and see when I was wondering around, music, painting, craft, dancing, a very nice family feel. Not exactly sure why this Carnival always happens just after the end of the academic year when all the students have returned home, is it a celebration by the locals that they have there streets back for the short summer period? Any idea's.
