Excellent idea! I belong to the Colorado Rifle Club. It is a great gun range but run by rather liberal people. I can only imagine their shock and horror seeing their liberal yards signs being used as fantastic targets. They’d probably tell me the plastic is not biodegradable and therefore not allowed within the soil conservation district. I think I’d take them all and post them at the corner of the road leading into the range property then call the original owners and tell them the gun range is banning them due to the soil conservation thing and watch the fur fly.
Those plastic corrogated signs take a hell of a lot of shooting!
