Fall is easily the best ... well when living somewhere that has fall. Here is Houston, we have either 2 or 4 seasons depending on how you look at it. (Summer, Still Summer, Yep Still Summer, and 1 week of Christmas. Or Hot and DANG Hot, whichever you prefer).
But up north the fall, when the breeze gets cool, the leaves change colors, the smell of burning leaves ... oh man, do I love fall. After that would be winter, and snow ... although I do know and remember that 9 months of winter is as bad as 12 months of summer ...
