In - out, In - out, In - out, In - out

(030528 Video Diesel in-out patio screen door) (This is short) . . I got tired of letting the cat and dog... in - out, in - out, etc, so I carefully rigged the door with counterweights, nylon string, and pulleys so it's easy to open and it closes automatically. Problem Solved. Both Tuna the cat and Diesel the dog can come and go as they please.

NOW, If I could only train the Chickens.
