oops....nothing wrong with my maths !!.....much !
Pit speed limit is 40 kph, or about 25 mph.
Racing has made it so that I can comfortably convert the two in my head. You can roughly estimate it at 60 miles is 100 kilometers. It's really closer to 62, but 60 is close enough. 300 kph is roughly 180 mph - but probably closer to 186 mph.
Plus, while I haven't lately, I often cross into Canada - where they use the metric system (like all sane people would). I've also traveled a lot, so I'm fairly fluent in both imperial and metric - except temperature. Other than a few basic degrees, it's a rough estimate for me. I do like how F is more refined at the whole number level, but that's possibly because I was born into it.
I am able to be on two world-class ski slopes within a 45 minute drive (depending on the weather). There's a closer one, pretty much in the village, but it's smaller and just opened back up again.
Alas, I no longer ski or snowboard. I was never good with either, but I had fun. Today, I don't dare risk re-injuring you femur. So, the only reason to go to the mountain is to check out the ski bunnies, and I'm happily married to a lovely lady that's many years my junior. So, checking out the snow bunnies isn't really a good activity for me these days.
