Scary Black Ice

It was December. Our son stepped carefully onto the black asphalt in the cold snap of his first winter in his new state.

"Why are you walking like that?" a friend asked.

"Black ice," he responded, well remembering foot and tire slips and slides on the tricky stuff. Then he straightened up, and grinned sheepishly at his friend, realizing that 60 degrees was, indeed, cold for Arizona, but most likely not cold enough to form ice.
