If I were in your position (no responses), I would look toward public land that you can access. Ideally, you want public land with cover for the rabbits as they are too easily taken by predators in open areas without the scrub for them to hide under. Rabbits need cover called "bolts" as when they are threatened, they bolt to underneath this brush for protection from birds of prey, coyotes, etc. Other places to look would be farmers fields where there is lots of stuff for the rabbits to eat. They seem to like alfalfa more than just hay, but if you can find an alfalfa field next to an area with cover for bolts, that should be decent hunting.
Rabbits seem to get diseases that run in cycles over some years, and I have no idea where they are in those cycles. Early this summer, I had a bunch of wild rabbits in my back yard, but it is a residential area, so no hunting there. The does were having litter after litter, but about a month ago, I think a coyote found one of the nest sites, and cleaned out a litter that was nursing. Hell, even coyotes have to feed their babies so I understand the cycles of nature. After the litter got cleaned out, our rabbit population dwindled quickly. I thing a coyote found easy eating, and cleaned out most of the rabbits..
