Did a bit of walking around Cuckmere Haven, Seven Sisters and Alfriston on the weekend. Have now done the editing, and found that lots of the area is well covered by Yahoo aerial, so I added some of the cliffs and water areas. I was surprised that the South Downs Way (footpath version) doesn't seem to have been mapped yet. I only added it as a name to paths, I think a relation will need doing sometime to link it all up.
