I prefer the cold weather to warm weather because you can always bundle up to get warm but I always find air conditioning a little to unstable to cool off. I used to always keep my house cooler in the winter, down about 65 or so but now that I don't have to pay for utilites I find I jack it up to a nice comfortable warmth. I don't know what that is though because I live in an old place and all the numbers are gone off my thermostat,
