The sky is FALLing on us

With apologies to Chicken Little, I just had to pay tribute to the sky. It is so gloriously offset by red and yellow colours as the leaves are turning. This is the most beautiful season. A poor limerick seems in order...

'Twixt summer and coolth-time comes Fall
(Or Autumn, as the colonies call)
When leaves are a turning,
then raked up for burning,
Red-flames on red-bundles small.

(Suggestions for a better 2nd line most welcome :-)
