You can order frozen rabbit feeders online if you can't get them locally. Obviously you have to pay for shipping but you're saving on gas and time. I get mine semi-local from someone who breeds them specifically as snake food, so they're already killed and frozen when I get them. I usually get 30-40 so I only have to pick them up once every few months.
Also rabbits should not be fed live, only f/t or pre-kill, as they have very long claws and can seriously mess up a snake even if the snake gets a perfect hit on it.
