Still working on a lock free task manager thing, which I pretty much got to the bottom of. Walked the dogs lunchtime. Early evening I drove over to Filton and did four geocaches. I then met up with my old friend Carl at the pub down the road. We then sat there for three hours and drank heavily. I got through six pints, he cleared of a bottle of wine and a brandy. We then came back here and killed off another bottle of wine. He slept in the guest room. This morning we both kind of felt rather rough.
