Hi Chaps,
Yes, ocifant, there is car parking up near the fort and White Horse. You need to take the road up the eastern side of The Manger, go past the Horse, and the parking is under the fort. This painting illustrates it perfectly:

As for recognition, Jane and I will both be wearing black bush hats, and there maybe a TMA flag/sign. We'll probably be making a lot of noise, anyway. Oh, and she'll more than likely have a sketchbook and be smoking Camels, while I'll have a camera and be looking louche. Possibly.
Looking forward to seeing you all!!! :o)
