It’s hard for me to really pick a photo that says “warmth.” Perspective on cold is different in Southern California, where winters approach but rarely drop below freezing, and the winter rains make December through April the greenest months of the year. So we don’t use fires much, and flowers and greenery make me think of the cool winter/spring weather instead of the hot, dry, brown summers. Even beaches make me think of late afternoon ocean breezes.
So I thought I’d pull out a shot for irony: An “Icy” warning sign somewhere in the San Gabriel Mountains, seen during the warmth of spring…when it most definitely isn’t icy!
