In Dallas, trees occasionally have toilet paper draped over them. I don't know if this is intended to be a trick or a treat. I have also lived in upstate New York and Los Angeles (Westwood), but I never saw toilet paper on trees until I moved to Dallas.
This is mechanical pencil on Strathmore Bristol Vellum. I started with a photograph of a house and some trees, which I modified for the purposes of the illustration.
