While you're around the Monument valley area, check out Valley of the Gods. It's a graded gravel rd that loops around. Look for the turn off on 163. Could be worth it.
The 4 corners monument is anti-climatic. We were there a few years ago and got a couple Indian tacos from one of the vendors there and sat down to eat it. While there, an Indian kid about 4 or 5, probably one of the vendors' kids, shyly peaked around the corner at us. Took us a while, but he finally sat down beside us and we talked for about an hour. Made a good friend that day. Cute kid.
