I've let at least 15 bucks walk and about 10 does walk since last Friday. I let the bucks walk because I get zero satisfaction shooting a buck that isn't mature nor has the headware 140'+. I let the does walk because I haven't really had a chance at a doe that wasn't so close to the rut. I figure I'll let them doe get comfortable in the area so close to the rut that maybe they'll come back with a buck on her tail.
