Doing a Christmas pressie swap, my mum and brother having gone to my sister's place in Newcastle from Aberdeen by train, the run south for me being preferable to the run north. Anyway, we'd expected snow overnight, so it wasn't a surprise in the morning. I wandered up to the main road to check on it, packed the boot with a shovel and blanket and our car snow socks and a flask of tea.
Yep, the road was bad around Berwick (especially coming back) but hey, it was passable with care. Which was the problem. Jeez there are some nuts around out there, sitting too close, wanting to overtake despite the queue in front for a good mile travelling at an easy 30mph. Coming back the police were turning people away from the Berwick bypass - they had a couple of tractors helping pull trucks up the hill. A couple of rear wheel drive cars u-turned into our lane and then slithered sideways up the hill with rear wheels spinning wildly.
Normally 1h45m each way. We were an hour longer heading south, and it took 4 hours heading back, but at no point was I worried we were going to get stuck (especially given the snow socks in the boot). Since then parts of the A1 have been closed (including to a couple of accidents, which, given the tailgating and overtaking I'm not surprised at...).
