I haven't in the past but that's a good idea. Will do this year and share. We usually just have the guys bring in their stuff a week ahead and then critique each other. Also, no real bad surprises that way! I do remember some ingenious things over the years. We said "bag" - one guy brought everything in a waxed paper bag - firestarter! Aluminum foil cups and pots around sticks in field. Homemade candle molded in paper cup with ten wicks - stove! You get the idea!
