Where's a white horse?

One afternoon in 1990 I walked a bit of the Ridgeway with 3 friends. I'd love to go again.

Husband is planning to take me walking the Ridgeway and Ashbury to see a white horse on Sunday. He says that he's found a nice pub to go to too, for lunch. It sounds good, except that he wants to be at Ashbury for 10 o'clock, and that's a tad early for me.

We'll have a discussion.
