We lived in Wis for several years. We had to buy our heating oil by the gallon. Yep scrape up enough $$$ for heating for the night (after spending $$$ on gas to go out in service all day) Yikes I detested those winters.
Now however we live in south south Texas and 60 to 70 degree winter days are just fine with me. We did have snow last Christmas eve. Now that was fun!
So winter depends on the longitude and latitude ... now winter in the US means summer down under --- that sounds pretty good too.
So below freezing temps for 6 months NO ... 60* for 6 months, priceless.
