we left a bowl of candy in a chair on the front porch and set out on a hay ride in the neighborhood.
I took 8 square bales of hay, some xmas lights, a honda generator, an ipod dock and some powered monitor speakers, a few dollar store halloween decorations and decked out an 18' trailer. Us and the 8 kids and parents that joined us had a BLAST. It was the best trick or treat outing I can remember as an adult.
My neighborhood does the same ('cept for the candy bowl) for New Year every year (when it's not too cold)
With a "progressive dinner" Three to five homes host and we start with drinks, appetizers, meal, dessert
and so on. We start 8-9ish and end at the celebratory house with some champagne and the toast. Loads of fun.
