When the sign says "Wildlife in the Road," assume that it means more than "they occasionally cross said road." They stand in it, lay down in it, and congregate in the road. When there is no sign, assume that some bison pushed it over while scratching.
When the sign says "Rough Road Ahead," assume that there are potholes the size of Rhode Island, washed out sections that have been replaced with gravel the size of golfballs, and miles of groves from ripping off the top layer of asphalt. When there is no sign, just assume it's the normal rough road.
When you see a sign that says "Motorcycles use Extreme Caution," just turn around and go back.
