how old most of doing lawn care? you can't hold your bladder until you come around a public restroom?
using the bathroom outside is something that should only be done in an emergency situation not matter what. personal or business situation.
my grandmother owns 80 acres of land with no houses on it within site. there is a wooded area on the 80 acres. when I go shooting I use the bathroom before I go shooting and I wait until after I'm done to stop somewhere or I'll drive the 20 min to the closet place in the middle and come back.
