This thing just keeps getting more complicated!!

More research done on the route again. I found out when I drove round the route with Heather and Millie a few weeks ago that the first 12 miles are so are prone to tidal flooding. Just how prone you can only tell on the ground when you see it - everything is flat as a pancake. It's rather akin to the Holy Island situation with the route at the mercy of the tide tables. I found out from the Easy Tides site that the expected time of departure on the morning of the 1st June is well within safe limits. I think.
