I don't know if it was the coolest, but for me it is the most memorable; Whether it was because my dad grew up on a farm in northeastern Texas, and living so far outside of town, he and his brothers and sister didn't really have Halloween in the traditional trick or treat sense, or because he had a horrible sweet tooth, (my sister and I used to sleep with our trick or treat candy underneath our pillows to keep him from getting all of our "good stuff"), my dad really loved Halloween, and when we were kids, he used to make our costumes. Being an engineer and lacking much in the sewing department, he would sometimes come up with some pretty elaborate plans. In 1976, when I was nine years old, he had decided that I should be a Jack-in-the-Box for Halloween. He spent weeks constructing my costume that year, and by the time he was done "engineering" my costume that year, I had a handle that turned, and when it was turned, it made that metallic music box like noise of an old fashioned Jack-in-the-Box. I had a lid, rigged with twine that I pulled from the inside so I could "pop" out of my box, and he had hand painted the outside to resemble an actual Jack-in-the-Box that had been mine. On Halloween, wearing a tie-dyed leotard and matching tights (it was the 70's and tie-dyed clothing was readily available) a color coordinated knit snow hat with a tassel from the previous winter, my ballet shoes, and red gloves, I stood rather impatiently while my mom used her make-up to paint my face like a doll's, complete with rosy red circle cheeks, and dad slipped my box over my head. I won a prize that year at my elementary school's annual parade and contest for most original costume, and everyone who saw me loved my Jack-in-the-Box costume. One thing dad had not taken into consideration though was how much room I would need to maneuver for trick-or-treating.. My box and handle took up so much room that when my sister and friends and I would approach a house, I couldn't go with them to the door, I had to either go first, or I would have to wait until they were done, lest I knock them off of the porch.
