I was in London yesterday for a few hours, meeting some friends. I managed to place a few bus stops (on Westminster Bridge and on Whitehall, though my coverage of these is neither pinpoint accurate nor comprehensive), a zebra crossing near Embankment and a couple of telephone boxes near County Hall).

A shame I couldn't do more but I didn't want to hold up the large group of non-mappers I was with ;-) At least I found out that it was quite practical to carry a GPS and camera with me and gather some odd bits of data when I'm in an unfamiliar city and busy with other things. I wasn't able to do a huge amount but I was still able to help a bit!
