I will not tempt you to do wrong! I will not!
As for snow in October. Well, let's just say, buy little cheeks a costume that fits over a snow suit. ;)
The malls here actually pass out candy so you can stay indoors.
Parents with hot chocolate and bailey's, walking around the block with their kids, dogs in jackets, snow pants, boots, scarves, they might as well not even bother dressing up, the people just answer the door, throw candy and shut the door as fast as they can so they don't get cold.
It's fun! :)
