My grandfather kept a rabbit gum set all of his life. I guess when he was young it was a way of life to survive. In these uncertain times of great depression and food shortages we need to take note of what our ancestors did to survive. It would be best to make one of these out of aged wood instead of new plywood. You can catch and eat many small animals for survival with one of these contraptions. You can bait it with apples or lettuce on the inside to entice the rabbit to go into the hole. A simple invention that works.
