1. Narrow boats. The canal was double parked for about a mile in honour of the festival.
2. Flags - people bag their spots in the arena field early in the day and mark them with home-made flags so their friends can find them. I spotted a pair of silver and black boxers, a red tee-shirt, a banner thanking the organisers, some giant sweets, three wobbly seagulls, rainbow whirly things, a jolly roger, flying pigs and wide mouthed fish.
3. Giant bubbles. A stall - which I never found - was selling a cunning device that made bubbles bigger than your head. They floated off in the twilight, reflecting a ring of stage lights.
