You know the kind.  Those nights when you think you are cool and can search around the local church building for some eerie photo opportunities.  The moon is shining brightly at first and then it seeks cover behind a blanket of clouds.  You walk out to the cemetery behind the church, and then your nerves kick in, even though you are still on the paved road, but very alone.  Every nighttime sound is a horror waiting to happen.  Your pace quickens as you return to the parking lot for one more photo and then a quick escape to the familiarity and comfort of your vehicle.  Whew!  That was exciting!
