If you have dualies and are heading for gravel roads, be sure to take a crowbar along. This weekend we headed for the back country and when we returned to pavement we heard a loud "thunk" every time the wheels went around. A small boulder had become wedged between the back tires and every "thunk" pounded it in even tighter.
There was no cell phone service available and we considered letting some of the air out of one tire to loosen the rock. Luckily a cowgirl drove by and she was able to get the rock out with her blacksmith tools.
