With son Cameron Buttery tucked inside the front wheel of the Rislone injector cleaner monster truck, Fred Buttery of Greencastle prepares to snap a photo of "The Defender" Saturday afternoon. The monster truck, owned and operated by Zach Adams of Bainbridge, was parked on the lawn in front of Auto Zone on Indianapolis Road, promoting Rislone. Adams and dad Greg Adams of Bainbridge built "The Defender" as a fully functional race truck. He has run it all over, "from Texas to North Dakota to New Hampshire to Florida," Adams said.
