OH Neal...what a TREAT!!! As a young woman I lived in London a short while....and I would walk from the home of folks I stayed with over to Marble Arch every day and back...and would stop and enjoy...great pubs on the outskirts for some 'banger and mash'...
What a lovely treat to have you for a guide, too...your love of the gardens came shining through!!!
Aloha,
Carol
