I used to do a lot of hiking (in Spain, France, and some other European mountain ranges). Many remote routes go nearby or through someone's fields or even properties (like through someone's backyard). There are many farm animals on the trails or just next to them. Fortunately nobody here cares and we are all more happy because of it
