Meandering pathways

Pathways like this one aren't predetermined by a "field pathway engineer" - they develop organically as people make their way from one point to another. Normally it's pretty clear that the pathway leads to some common gateway or meeting place.

What is interesting is that while one may expect the pathway to be straight they tend to meander to their destination. Perhaps I'd understand this if the same person walked the route each day, but this path was made by a variety of people. What made them all meander in this particular pattern? It's not like there are hills or other obstacles in the way.

Is it only me, or is this kinda crop-circle-strange?
