Roger, try the AA their route finder seems quite good. As for where Reedham, draw a triangle joining Norwich, Great Yarmouth and Lowestoft. Reedham should be somewhere in the middle. Just hope the venue is the right side of that dammed ferry (least I think that's Reedham).

I'm toying with the idea of getting down for a bit of it - will have to see what the weekend brings.
