Don't like:
1) Frostbite. (I used to bicycle to highschool in -35°C (-31°F) weather, and that wasn't fun, since you couldn't breathe.)
2) Strong, cold harsh winds.
3) Shoveling mounds of snow.
Like:
1) Cut down on beer (beer is only REALLY good if you drink it ice cold on hot days after doing physical work). Hot tea and hot chocolate in winter.
2) Rye whiskey.
3) Skating with someone special (gotta find someone special first).
4) Family get-togethers at Christmas.
5) Why would you go on a warm vacation during winter? Who doesn't love snow!?
