Why are SANS trails safe? They are clearly marked and well-defined corridors with few dangerous surprises. Because they are groomed and used regularly, overall they are smoother and wider, with better sight lines and fewer hazardous corners, intersections, inclines and obstacles. Most water crossings and ditches are bridged and water/ice is usually staked, marked or tree lined. Traffic signs are prevalent throughout the system to give riders as much advance warning as possible of trail conditions ahead.
