Definately as I am very envious of those that attended this one. In answer to your questions Swordsy, for me, preferably Oct - 2nd or 3rd weekend, and either below Collingham or above Holme Marsh, but having said that I would have no issues with it being at Collingham or Holme Marsh. I would prefer it to be when there is a bit of extra colour in the river after all the hot weather has passed.
