Body hardening-degrees of acclimization

I think the opposite is true for me. I quickly get used to the warmer temps, and can't believe I was able to ride comfortably at 20º F. When a cold day comes after the warming trend, I over-layer because I'm quick to freeze.

Vancouverites who have never lived elsewhere in Canada, complain that 20 degrees C (isn't that what you meant, redhodie?) is hot. That would be the approx. norm for Vancouver peak summer season.

Give me a break, I consider 30 degrees C at 100% humidity hot and common in Ontario during summer.
