Colin would only wear a costume if it came with weaponry. I think Charleton Heston is his president. He even put down his pumpkin and shot some people after they gave him candy...smart to shoot AFTER they handed over the goods.
The boys enjoyed full, heavy pumpkins, being recognised for their costumes and watching people use a potato gun. What more could you ask for!? We enjoyed short distances, flat sidewalks, few cars and a bonfire with beer. Its a win-win situation if you ask me.
