Driving up to the summit of Mount Constitution, the road twists and turns a great deal. Some of the curves have a steep drop off which will not end well if your vehicle were to leave the paved surface. Consequently, there are plenty of concrete posts along the edge of the road to try and stop you going too far wrong. However, it is so shady and damp within the woods the cover the side of the mountain, these posts get no light and have become home for moss. It looks so thick that you wonder whether the car would even be scratched it you hit one!
