Cycling through fresh snow is fine, it’s the snow that has been driven over and compacted that’s really slippery.
When you ride over the slippery icy stuff, don’t brake hard, don’t make any sudden turns. Better to just stop pedaling and let your bike roll. Watch out for hard frozen ridges of snow.
Usually the cycle paths are salted early, it’s the part from the busy cycle paths to your front door and the last bit to your destination where you have to watch out.
Snow dampens sound so be careful around cars, you might not hear them coming. If you wear a coat with a hood it might be more difficult and annoying turn your head, resist urge to not look when crossing roads.
Summertime is terrible, especially in summer. You have one less usable hour in the evening.
During the summer you cannot really go outside until the sun goes down. It’s simply too hot in direct sunlight. Summer evenings are nice, after the sun goes down and the world starts to cool down a little. By moving the clock forwards we have an hour less of usable outdoor-time. It also means you have less time for things to cool down before going to sleep.
DST makes it so you have to go bed too early, being unable to enjoy the evening, and when you go to bed it’s too hot to sleep, but you have to because you have to get up at a ridiculous time the next morning.
Instead of DST we should introduce MST (Moonlight Saving TIme) and move the clock an hour backwards in summer. Then we can actually enjoy our summer evenings and go to bed once things have cooled down a little more. The earlier sunrise doesn’t matter since there is such a thing as blackout curtains.
