I must admit I cannot handle the heat. 75F max is fine by me. Went to Jasper(4hr drive west of us in the mountains) recently and climbed a mountain trail and towards the top trudged through the snow. Along came a series of thunderstorms and a big clap of thunder, a bolt of lightning followed by hail made us hit the deck and put our hiking poles on the ground. I put a head warmer on and my wife put her gloves on.
Now that was cool. Would not and could not do that in winter!
