Yesterday, I bought a trip computer for my bike so I will know how far I've travelled throughout the day - otherwise, with frequent stops for sketching and very few road markers along the way, I would have little idea how to pace myself. So today, I did two of my regular rides to confirm their lengths and on the way home from the second, stopped to catch the last of the sun on these trees. I walked my bike over about 3 metres of grass and then, to my horror, noticed the tyres were stuck full of those dreaded organic drawing pins. I thought I might just be able to get home before the air leaked out so I sped away - and have just done this from memory. Seven holes in one tube and 6 in the other - it's back to the bike shop tomorrow for another pair of of spare inner tubes.
