I have a similar scenario. Near my house there is a nice 2mile road alongside a lake that has a dead end. At the dead end is a mental health center that specialized is eating disorders (anorexia. bulimia) so there are are always a bunch of unstable skinny people around there. Well if you run through the campus (on the driveways and parking lots, about 1/4mile) you come out on a road that goes up the other side of the lake and then you can make the route a 7mile loop around the lake.
My wife, who actually did a nursing clinical at this same hospital in college, thinks it is inappropriate to run through there. Am I immoral?
I actually think this is worse than the graveyard thing. Lots of those people with eating disorders have probably used running as a means to achieve their distorted body image goals. Seeing a fit, healthy, presumably skinny runner might encourage them in the wrong way.
