This is what the sky looks like.... when it's getting too dark to hike.  You should probably be heading back to your car, instead of continuing up the canyon, further into the wilderness.  I, however, am not a prudent individual and proceeded to lead my friends deeper into Will Rogers State Park, take just a few wrong turns due to confusing trail markers, and have to explain myself to a quite disgrunted park ranger.  Whoopsie.  Thank heavens for the almighty headlamp and our adventurist spirits.
