Summer! The only time of the year that it gets above 50F here. I love me some blue jeans, but I kind of get sick of the weather when I can wear them 90% of the year.
both. they are opposites and both have awesome qualities. (in my opinion) summer: you can swim, it is hot, no school.....and on and on winter: skiing and snowboarding, ice skating...to forever...
the thing is, i couldn't live in a constant summer or a constant winter. so having the seasons change is perfect. just the way it is.
Really depending on where you live, but I love winter! You can do it all except water, ice is my element, and winter is the funniest, manliest time of the year.
