Abstract: The invention is a hunter's personal safety game pack and method of making it. The game pack is especially designed for the wild turkey, with a bloodproof bottom pouch, a No-See-Um mesh drawstring bag top, and a shoulder harness. The wild turkey is a large bulky bird, weighing approximately 10 kilograms. It is cumbersome and messy, a burden to carry without a game pack. Carrying a wild turkey using one hand in the traditional over-shoulder position puts the hunter in a very dangerous situation. Carrying his gun with one hand is not recommended for safe gun handling; the exposed turkey on his back invites other hunters to shoot at the turkey and possibly shoot the otherwise successful turkey hunter in the back or head. Perhaps even more important, Lyme ticks may be transferred from turkey to hunter, with risk of the disabling and sometimes fatal Lyme disease. The taken turkey must cool quickly to avoid spoilage. The No-See-Um mesh top permits cooling ventilation without permitting any ticks to pass.
