I was thinking about the route. How about meeting at the London Eye and then walking along the South Bank to the Tate. There should be some interesting stuff along the river as well as some traditional skyline opportunities. In the Tate you are allowed to take pics in the turbine hall but not in the actual galleries.
Outside the Tate is the Millennium Bridge which makes for some interesting shots, and then St Paul's (not sure how much scaffold is on at the moment...).
From there people can take the tube wherever they need to go, or walk though the city or back across and to Waterloo the way we came.
I was thinking about making it later in the day to try and get some more interesting light. Perhaps starting at 3 or 4pm?
No more replies so I'm afraid to say this Saturday is cancelled. I have it on good authority that a walk organised by one of my twitter buddies is going on on the 6th June.. stay tuned for an update on that one.
