Tomorrow I might take the bike out for a spin, or another walk to quieter climes - I need to find out if there are any other events in London that might be worth a visit.
Right now the noise level is wobbling around 45-50dB, which isn't that much more than usual, apart from the last few whistles, horns, etc., and there don't appear to have been any serious incidents, so I think I can say it's been a pretty good day.
