Tonight, AKBmzawy and I will have the fire pit going in the driveway.  We will be wearing some warm clothing due to colder temps here in MO.  Candy has been bought.  Looking forward to the trick-or-treaters.  
Last year, the best costume was by a 9- to 10-year-old girl as a zombie bride.  She went all the way with the makeup and blood-stained dress with torn edging.  Very Hollywood quality.
I do ask some of the kids what they are due to not knowing current cartoon characters.  Spme due to original imagination costumes.  
The infants and toddlers love the fire.  Make sure the toddlers don't rush to the flame with outstretched hands for the warmth.
Unfortunately, my Darth Vader costume is packed away.  I haven't modified it for my amputated ankle and foot yet with new boots.  The lightsaber needs 6 new D cell batteries.  I stoll haven't got the voice device to speak like Vader.  I'm 5' 10" and a short Vader.
