Understood–but gasoline has a “shelf life”. After 30 days, it starts becoming less and less volatile. Over time, it becomes like varnish, and nothing will restore it to a useful form. Sure, they’ll get some, but if you’re far from a major city, and not on the main highway, their unfamiliarity with your neck of the woods will cause them to hit only what’s easy. Eventually, they’ll run out of fuel.
