Lewis and Clark carried an air rifle on their expedition to explore the Louisiana Purchase.
I have a Ruger Air Hawk. I bought it because I had too many squirrels in my back yard. I have an oak tree in my yard that always produces a lot of acorns. The squirrels were cute until they became destructive. One of them got under the hood of my daughters car and chewed the wiring to her headlights in two and chewed holes in the tubing for her windshield washers.
So far I have killed four of the little beggars with it.
(Luke 11:21 KJV) When a strong man armed keepeth his palace, his goods are in peace:
(Luke 22:36 KJV) Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.
