Yes, an old fashioned slingshot! Carry one in your pack; they are light weight, nearly silent, and a great asset when hunting. You can harvest a grouse silently, shoo away a noisy Jay, thump a crow or silence a rowdy squirrel! How many times has a persistent Steller's Jay or tree squirrel ruined the productivity of your stand? You don't want to move, and you also don't want to shoot a firearm. A good old fashioned slingshot is a lightweight, inexpensive, and fun answer to these annoyances.
