Yes, we need more information. We need an amateur video of a 70ish year old woman in a pair of too tight shorts, sleeveless shirt and flip flops, smoking a Marlboro Light.
She should be seen in the video walking along the mystery tracks, pointing and waving at the them (with the same hand she's holding the cigarette in) with the same enthusiasm of child playing hide-and-go-seek.
There should be a narrator remarking about her every move (oh, almost forgot; she should be a bit portly).
Okay we've set the stage. Time for performers.
