You can hunt almost anywhere for rabbits depending on your area. If predators are high in the area you hunt it may be a little tougher but I usually have good luck hunting fence rows, around barns, farming equipment, tree lines etc. Rabbits are usually everywhere. You don't really need a dog though it does help. I usually hunt with my brother in law and we take turns kicking around brush to kick them up. When hunting fence rows usually one of us walks right next to the fence row and the other walks about 5 or 10yards awayto take the shots when a rabbit jumps. I use a 12 ga with6 shot and a modified chokebut a .410 would work good too. I wouldn't use anything bigger than a 12 ga though. Justbe sure to aim for the head when you take the shot so you don't ruin the meat in the hind end or gut shot the rabbit.

Good luck, hope this helps!
