I went to visit my parents for a bit (actually, the specific timing was dictated by a dentist appointment) over the weekend. Weather was a bit cold, wet and windy but was tolerable for walking around outside with a big coat on.

I managed to map some more residential streets around Prestbury, which is the location of this diary entry. My mapping here is a bit sparse, I was walking with my parents who are "mapping muggles" and don't really understand why I'd want to walk up and down pointless side streets. Prestbury was always bigger than I perceived it due to the housing estates around Noverton Road which I hardly ever went into. It's now even bigger due to new development...

I discovered we'd driven down an unmapped road on our way back to Cambridge. Unfortunately the path of the road that I'd GPSed (my trace looked pretty sane and smooth) conflicts with the North part of Copt Elm Road here:
osm.org/?lat=51.88982&lon=-2.04615&zoom=16&layers=0B00FTF
I suspect the existing data is not entirely correct since my GPS trace overlapped the roadways given in unlikely ways. I'm not able to correct it as I can't go back to check the junction layout. If nobody does it in the meantime I expect I'll take a crack at it when I go home for Christmas.

Back in Cambridge, we got mildly lost and came to an entrance to an allotment. I was then able to find the site on the Yahoo imagery for Cambridge and trace roughly round it, which should appear here:
osm.org/?lat=52.23021&lon=0.11531&zoom=17&layers=0B00FTF
another empty space filled in, hurrah!
