Look for green briars, thick enough to tear you to shreds walking through them, these provide good cover. Once found, walk through them.
Stop frequently and scan the ground, looking for rabbits or rabbit eyes. They will sometimes sit tight and let you walk by. If you do see one it will likely explode from its position. Alternatively they will come into sight when you are in a tangled mess.
Small patches in open areas can sometimes hold a rabbit but largely you should look for big patches of briars.
My favorite quarry is rabbits, hunted them for years with and without dogs. Money spent on rubber boots and good tough pants to protect your legs is money well spent. A good hunting jacket that also protects you is also good. Look for ones with the washable pockets on the inside around the waist.
Rabbits will start to pair up at the end next month as/if the weather warms a bit, and they will be out and about. #6 shot in an improved or straight cylinder is a solid bet for a gun.
Crane is big, too big for my taste but there is conservation land all over the cape where briar lined trails exist. Rabbits can be found in scrub oak and around rock walls, hedge rows etc, but I like briars. If your legs arent bleeding and cramped at the end of the day, you're doing it wrong.
Best of luck
