A quick update on my progress. My aims this year were to attach my Reading mini-cluster to the main cluster, get the main cluster to over 1500 tiles and the square to 30x30. So:
Not only did I attach the Reading mini-cluster, I also pushed the main cluster out in the other direction as far as Abergavenny. Admittedly it now looks a bit like Mr Tickle, but whatever.
Largely due to the above, my cluster total is now well over 1600.
The square proved to be the difficult one. I was sitting at 29x29 for a long time, and I had a ride planned to push the square out a bit further. One of the roads just brushed the edge of a tile, and unfortunately a bit of GPS wander meant that my track didn't quite get into it. So it failed. Today I have finally been out that way again and went up the dead end on the other side of the tile to make sure it would register. So, 30x30 achieved. Whilst I was out that way I thought I might as well bag another tile to push the square up to 31x31, and after a bit of comedy off-roading along a very squelchy path I have that too. So targets achieved.
Now I just have to think what to aim for next year...
