Shhh don’t tell anybody about the Twin Cities!
Doesn’t the twin cities have snow and cold winters? They could use that to similar effect.
I think the biggest thing people have to get used to is that there is roughly a 120F temperature swing from January to August.
-10C is 14F, which I agree is a pretty nice day if you're properly outfitted.
Honestly, the coldest winters I spent were in Southern China, even though it was 5 to 10C out, no indoor heating really sucks and will beat you down quickly.
