I've seen "fake snow" in magazines. Thought about sending some to GS in NV. He doesn't remember snow- he was only a baby the last time he was here in winter.
I sent him a bucket of snowballs last year- little fuzzy pompoms in a bucket. And snowmen magnets for the the fridge.
Enjoy your fall- it's weird- I knew EXACTLY what you were smelling- I could "picture" it in my brain.
