Overcast and nippy. The bit of moisture in the atmosphere makes all the difference.
It is a weird sensation landing back in sea-level Toronto from arid, elevated Calgary. In the hours after getting off the plane I can feel my body sucking in the moisture and oxygen from the air.
I discovered a funny thing: our eldest was over in Calgary recently and I was cooking dinner. I asked him to look at the pasta packet and tell me the cooking time; which he did. But the pasta came out nearly crunchy. So, of course, I made a sarky remark. Days later, however, it was pointed out to me by some students who were trying to get plastics to deform in the way they wanted them to, and were failing repeatedly, that that water boils at a lower temperature in Calgary. This explains a very great deal.
