I'm visiting London again this friday for a whole weeks stay. Is there
anything interesting transport-related I could catch while I'm there? I'm
also open to other suggestions. I have tried to compile a list of what I've
done so far at jarle.com/london/ .

I'm considering doing a section of the London Outer Orbital Path. Any
suggestions as to which section? So far I'm considering section 12
(Uxbridge to Harefield West) or 20 (Chigwell to Havering atte Bower).
