The gas line runs along side of the house next to the water hose that supplies the reel next to the tank, they are both covered to protect them from any damage. I have ordered some quick disconnects but they haven't arrived yet. As far as security goes well...I have 4 dogs plus we live in a nice neighborhood in a nice town close to the square and high school which means lots of police patrols (kids like to drag race one street over due to being a nice straight stretch). Any belt sanding is done in my shed and grinding/cutting is done outside the "shop" area" normally at the other end of the carport facing the driveway since that is where the other outdoor power outlet is.
