So started at a reasonable time. Did a few more GPU grabs of stuff, then into another rehearsal of my wonderful presentation. Walked Sasha. Then started on an SDK upgrade, which going by compile errors is going to take a while. Walked to a new Geocache, which I didn’t find. It’s getting bloody cold again. Weather at the weekend is looking decidedly dodgy. Did some more exam prep. It’s odd, meteorology is a bloody great book, navigation is even bigger and human performance is about twenty pages, yet they all have the same amount of exam questions. Still, all need to be passed.
