Why not meet under Tolkien's
pinus nigra in the Botanical Gardens? It's just off High Street by the river, which would provide a meandering walk to Lady Margaret Hall.
As I recall, even with a bad knee, most of Oxford was quite walkable, even from the cemetary to High Street. That includes the B&B, the Lamb, and the Mitre.
If only there weren't those protestors at Heathrow complaining about all the polluting air travellers! And only if such air fair were more reasonable.
I suppose I could set up a paypal account and ask for donations for the travel costs. I recall
burrahobbit doing that. Think it would work for me? Will Downers help me make my way East?
