Ok, this is a little ambitious, but at the end, it will require that the "costume wearer" never needs to be physically present. I was inspired by the phrase #2020TrickOrYeet. My premise is as follows:
Over the three or so days prior to Halloween, set up small pails with Non-meltable halloween treats throughout the neighborhood, ideally covered so animals can't get into them. All must have the following note:
"#trickOrYeet from your favorite flying witch".
Make it look like the pails landed hapharzedly (sp?), like they were thrown from a great distance.
Get a really powerful slingshot. Like, crazy powerful. Or a drone. Wrap a bunch of christmas treats in a soft cloth like wrapping so they won't hurt or injure anyone if dropped or thrown from a great distance. Then, let 'er rip on the big night
