I agree with driving roads.
Usually, when you come to an area that has one or two....you'll stumble across more and more. Perhaps not the same day, but they're there so remember them for the next trip.
It'll probably be a pretty good trip if you come home with more than 2.
I'm lucky enough to have access to a farm not far away that has a sizeable population....unfortunately, it's also in a firearms restriction zone (no centerfire/rimfire).
This year, it's bunny attack by bow!
