On my property, I installed a 12' wide driveway on the edge of the property line all the way to the back of the lot. My property is a large rectangle, 120 X 210 feet approx. Except at the front, no one notices the driveway, because I have a 6 foot hedge all the way back as well. No one cares about where its parked because my neighbor on the closest side do not use that portion of the back yard anyway. So, if you can install a nice sand gravel driveway to the back and no one has a primary view out your way, just go ahead and do it. Then have a BBQ and invite the whole neighborhood!
