I think if you have access to secluded areas like JM did, in the woods you think about possible areas to do whatever it is you like doing. Could be hunting, camping, finding a place to smoke pot, take girlfriends, or as he got older probably started thinking of more nefarious things that most of us would not think of.
I used to go running a lot. Once I used to live in the DC area and there was a nice walking/jogging trail by my apartment. I went running there once and it freaked me out cuz it looked like you could easily hide a dead body there. A few years later, presto..Chandra Levy.
oh em gee
As a semi-pro photographer I'm always noticing the scenery around me..looking for a great "shot." I'm sure people like JM are always looking at the scenery too...thinking what a great spot to get rid of a body.
gross
