York is great, Oxford is physically beautiful but human factor interferes with that--street people are like Berkeley. Christchurch College is spectacular however.
York; great people, lovely physically, great pubs. Loved "Hole in the Wall" pub near gate; loved Cathedral (truly awesome). Visit Castle Howard 15 miles away; don't think it's mentioned in book but awesome (take train then taxi if no car). Where they filmed "Brideshead Revisited".
Loved Chipping Camden and nice pub just off main drag (forgot name, but you'll see it). Hike Dover Hill.
Didn't bother with London this time.
Do you know of any decent hotels/BB's in Cambridge? Will try that next time. The 2 mentioned in book don't work out for me.
