The answer is simple: in Switzerland, they dye eggs to tell the boiled ones from the raw ones. Clearly, their mom didn't teach them in childhood that just giving it a spin is enough: the inertia of the liquid will make a raw one spin slowly. On the other hand, life is more fun when your eggs are colored. I think among metrosexual hipsters it'll soon become trendy to not just shave, but also dye, powder, and draw eyebrows on their balls.
As for Lake Zug, I got there quickly, but for some reason, I turned counterclockwise. I didn't want to think too hard about where and how to ride. That was a blunder. It turned out that for a good chunk of the route, the bike path is very narrow. Moreover, it runs as part of the mountain road, but on the left edge, and is separated only by road markings. So I was riding against traffic (or on the road on the right). The locals, naturally, are in the know, and ride around the lake clockwise. Things like that are hard to predict in advance. A friend had told me (he rides this route a lot), but I didn't realize it was crucial info.
I was in no rush, since it was only a 40km ride. I'd pop into various places if they looked interesting. Eventually, on one of the gravel paths, there were a lot of pedestrians with dogs. The first ones I met, some young girls, held their dogs back so I could pass. But the next ones, some old ladies, cursed in annoyance in German. They signaled that I didn't belong there and should get the hell over to the bike path visible nearby. I nodded to show I understood. Even so, as I passed them, I heard an unflattering "idiot". Apparently, the word is international. In my defense, I'll say I definitely didn't see a sign that the path was only for dog walking. I purposely looked carefully, as I didn't want to get a fine or get yelled at, but I still got into trouble.
So I returned to the good old bike path, full of pensioners on e-bikes. It's cool, what can you say — not everyone's health lets them tear through the hills on a regular bike at 70, but here, go right ahead.
The lake would come into view and disappear again, the railway tracks ran alongside, and there were a lot of houses along the way with signs saying "Private property, no driving or walking through." I'm not a fan of them. It's a shame when a country is so privatized that you can't even walk up to the lake. Why do natural resources belong to whoever staked a claim first, or whoever has dough pouring out of their ears? It's stupid and unfair.
