Found this route by mistake but my god theres some great twisties all the way along!!
Great way to blow off an hour. Duck pond from cawood through ryther is great little tight bends but no bushes so you can see everything for a mile or so, be careful though, recently resurfaced (aug 2011), it'll be like an ice rink for a bit!! There can be quite a police presence at times (particularly hiding in the bushes on the stretch between the a19 and cawood)
