But will that kind of person really carry trash until a resting place, or maybe just dispose of it where they open stuff?
I personally always found trash cans in areas not commly frequented by cars rather odd - I got tought in the 80s and 90s that we are careful how we pack things we take with us when hiking, and take everything back.
It is a conecpt a 3 year old can understand (I see that now with my own kids), so you’d expect an adult not to have a hard time with that.
