I guess that's personal preference. Growing up in Indiana, we hit 100+ in the height of summer (and humid as hell) and subzero in the winter... While I don't _enjoy_ those extremes, it does really lend to a sense of time passing and makes the really nice days throughout spring and fall that much more enjoyable. I miss waking up on Xmas to a foot of snow, despite not enjoying snow, and having to huddle around a fire to warm up after being outside. I hate the cold, but I dig how it brings people together. As for the heat, you'll never appreciate a cold beer or lemonade (or both) like you will after mowing your lawn in 90+ degree weather. And those first few days of spring where it's light sweater weather in the morning and then 80 the rest of the day after having just braved a winter of snow and freezing temps? That's my favorite time of year.
Clearly I'm nostalgic.
