Zlin526, Thanks for correcting my rather poor geography - thats why I put the question mark in after Essex. Hope I've not insulted anyone in either county!
Your description of Nayland is spot-on but I should point-out to anyone who hasn't been there that the "upslope" at Nayland is the steepest I know of anywhere in the UK. (Waits to be corrected)
I've always managed to get airborne before the start of the downslope but I've often wondered what it feels like to go over the "edge" while still on the ground.
