Has to be Autumn, followed by Summer. But each has its own charms. One thing I don't think I could do is live someplace where the Season is the same year round.
Spring (Gardening Time) Fall (Cool Temps and Beautiful Colors) Winter (Snow) Summer(Love the summer activities, Hate the Heat and Humidity)
“Our hearts grow tender with childhood memories and love of kindred, and we are better throughout the year for having, in spirit, become a child again at Christmastime.”
That's a bit hard for me to answer, because there's aspects of all of them that I love equally. I'm going to have to say that spring and autumn are both my absolute faves; spring for its rains, renewed life, thunderstorms, and Easter...and autumn for its holidays, smells, and colours.
