Sammy loves to ride in his sidecar! This was just a test run of the sidecar I built for Sammy. I got the idea one day after I started the riding mower. He bolted out the doggie door and jumped on with me. It doesn't matter if it's a tractor, mower or quad runner, if the engine is running, he plants himself intently and won't budge until the engine is shut down. Spoiled?....Maybe.....
