Well, I confess I'm feeling knackered. I was on the road by 5:25 to collect some data from one of our works and then down to Bristol. Any later and I would have been caught in traffic hell. I then didn't get away for the journey home till five thirty - no, not five minutes later. Finally home by seven, that was me done for the day. Might be another iffy one tomorrow as well though. Feeling sleepy and it's only eight!
