Went out for a lovely evening cycle ride to do some mapping, and managed to complete Wentworth, Coveney, Wardy Hill and Witcham, as well as finishing off Haddenham which I started a couple of weeks ago. Unfortunately I had a couple of problems - firstly, as I finished Haddenham I checked that the GPS was still running and it wasn't - leaving me with an unknown amount of data to repeat on a future occasion (it was beginning to get dark by this time). When I got home it seemed worse than this, as I couldn't initially find the tracks at all. however further investigation revealed that the clock had somehow got reset, and it had indeed saved the tracks but as the name starts off with the date, it was completely wrong. I uploaded the main track to discover that I had lost only four residential roads as well as the circumnavigation of Haddenham recreation ground - not too much, but annoying as it will require a return trip to complete it. I had made a note of all the names, so I've added them to the map as best I can from memory with a note that they need resurveying. Fortunately
