By far, cold. Been in colder weather all my life. I laugh when people in disneyland think 70F is cool to cold. I can always find ways to warm up--sometimes even get hot.
Gone out in the snow in my boxers and barbecued.
Don't get me wrong, I like hot as well, but in general I am not as well adjusted to it.
A dry cold atmosphere is best IMO. Especially if it's up in the sierra nevadas with all that snow. Boarding and skiing. Magical. Even at -13F.
Funny how down the hill on either side it is just rainy and windy. CA is more open to the ocean, so you have the added downside of humidity. NV is not humid but the winds tend to be more dangerous.
I just don't care for fridgid cold without snow anymore. My swordplay friends all call me General Grievous because of my coughing, wheezing, and hacking in those conditions.
