We had 15 mm of ice on the lake in my local park (Treptowerpark) on Xmas day yesterday, but overnight we have a -10° C freeze, and it had a super hard super strong 40 mm surface on it today 🙂 It’s a bit bumpy, but nice to be back on the ice again! I didn’t stay on long, because there were too many people around, and there’s usually a bunch of idiots who follow me on without knowing what they’re doing, and I didn’t want to have pull the dumb arses out of the water.
