You can hunt public land using a car. Just clean the deer wherever you killed it on the wma and then all you have to bring home is a cooler full of meat. If money is a concern I highly suggest public land. Hell, I have my own family land as well as land I lease and I still like to hunt public land from time to time. It's an adventure. You feel like you are hunting a true wilderness. 90% of the negative stories you hear about public land hunting are either lies, exaggerations, or told by people who have no idea how to hunt.
