Mithalwen, if you're planning a trip round Sarehole and that area I'd recommend getting that Bob Blackham book, Roots of Middle-earth:
http://www.amazon.co.uk/Roots-Tolkie...1370360&sr=8-3
I thought you went to something else instead of his talk at Oxonmoot 2006? Or did you? I think that was before you identified yourself!

But he really knows his stuff doesn't he? I'd recommend this to everyone. He's a Brummie, a local historian and a member of the TS. It's a fab book and not only is it enjoyable and gives you a thirst to see Sarehole and the other places Tolkien knew, but it's also a decent guide.
And it's only £10.99
