Tuesday: started work on detailed mapping of Newmarket, Suffolk, dealing with the race course and the residential areas to the north and west. It'll take a while - population about 15,000 so about 15 hours of surveying of which I did about three this week, so maybe 5 visits should see it done. It's only 10 miles from home though, so a bit more accessible than the remaining bits of South Cambridgeshire out towards St Neots.

The racecourse and related paraphernalia involved quite a few tags I'd not needed to use before, but much of the rest of the town in this part is rather dull ex-council housing residential (there's also a large industrial area which I didn't really start on, straddling Exning Road).

Discovered the Newmarket end of NCN51, which leads from Exning all the way into Newmarket town centre, most of it entirely away from the road down a small stream valley, so that got me back to the station and got mapped into the bargain (someone had obviously tried before, but maybe got lost, as it tailed off in the middle of a housing estate).
