I posted a map in Thread 14 (pg26) and Thread 13 (p44) of the large Soil Conservation Service Site 2a Reservoir just north of the church. I'm entertaining the theory that Swatperp ran from this end of the church into the darkness, tossed helmet and swat clothes into large trash bag (folded up in pocket or chest pack), weighted the bag down with some rocks or the like and tossed it into the reservoir. Then continued "jogging" in jogging clothes to his morning destination, showering there.
