I think I stopped at around 11 or 12 years old. When I was young I got too tired out to Trick-Or-Treat. By the time I walked to three or four houses I was done for. Sometimes my Mom would pull me along in a wagon, and then I would just walk up to the door. A lot of years though my sister went out with an extra bag for me. I always loved dressing up though and I would go to the neighbor's house next to us and they fixed up bigger treats for me.
I still love Halloween and dressing up to hand out candy to our neighborhood kids.
