We saw some of the of "extraordinary open air moments" of Watford festival. One of my favorites was 'Glisssssssssando Opus II' - a troupe of musicians who played great music whilst gliding smoothly in formation, puffs of smoke rising from their funnels. Surreal and wonderful.
There were roaring dinosaurs loose in the street (sorry Simon ;-), which certainly livened up a damp day in town.
The skilled stilt walkers (try saying that after a couple of ciders) made it look easy but it must have been exhausting performing in huge swaying costumes. Heads swooped to peck at children and forage in the flower displays, a grocer's stall and among drinkers outside a pub. Made people laugh though you had to watch out for the wildly flapping tails!
There were other really good performances and experiences, such as the onboard show 'Tug', which Simon has written about here :nbtortoise.blogspot.co.uk
