Sue, I would do what my father did: I'd work 2 jobs. If they had to be minimum wage then so be it. Yeah, I'd rather hunt too, but a freezer full of deer meat don't put shoes on the kid's feet.
Poachers are thieves. It's too bad your vet didn't get their license plate number. The state would have acquired a new pickup, some guns, and a good amount of cash (assuming your state laws are similar to the laws here.)
