Hilarious! Well the list of where not to try that could be very long. With the gravel, there could be many opportunities to cross the road with no problem.
My cousins lived on a larger gravel road, a county road, and one summer they lost 3 dogs who chased cars. That can be a dangerous sport.
One of the dogs I watch chases cars if given the opportunity. As a result, I always park by the curb where I load and unload her.
