Isn't that the truth, and in most parts of Canada as well.
I've had the most amazing experiences flying in cold winter weather, with snowcapped mountains, frozen lakes and rivers and trees encased in snow below me.
On the other hand, some of the most mundane as well as uncomfortable flying has been in dreary, smoggy, hazy, turbulent and unstable summer.
Between the two, I'd take a cold dry winter's day, over a warm summer's day in a heartbeat.
