Well it appears that land must be "farmland" in order to bag a deer on it without a license (not sure if this applies to buying tags as well).
Here is a post on the subject, presumably by a CO:
"Guys I don't make up the answers I give on here nor do I write the laws. When a question is asked I post the appropriate statute. If you read the statute it is very clear on who can hunt without a license. However I do not know of any Officer that is going to tell someone they cannot hunt their own property without a license. I can only speak for what I tell individuals in my assigned county and the "general opinion" of Officers in my district. Everyone needs to throw the acreage factor of the question out. There is no acreage requirement to hunt on your own property. When someone asks me if they can hunt on their own property without a license the first thing I ask is if they farm a crop. If the answer is no then I generally ask if they have ever had it timbered. If the property owner has been timbered then in my opinion they have used that property for the production of timber. If they have never sold timber off the property or farmed a crop I then suggest they plant a garden or some fruit trees which would suffice for me to qualify for the production of crops or fruits. As far a leasing a property I do not believe it is the intent of the law to exempt individuals from purchasing a license that lease property for the sole purpose of hunting. The correct short answer to this question is no you cannot hunt property without a license unless you meet the requirements listed in the statute. However you need to contact your local CO to get his opinion on this topic. One thing to keep in mind the Hunting Guide is just that a "guide". It does not have all of the appropriate regulations required to be able to enjoy the outdoors legally. The guide is a generalization of important statutes but for more detailed information you need to visit the state website www.in.gov and review title 14 and Indiana Administrative Code 312.
On a side note: Steve maybe it would be a good idea to only allow a moderator to respond to questions in this forum. After reading all the "armchair Lawyer" responses even I am confused. This is not intended to be disrespectful to those who offer their opinion but would cause less congestion in the forum when a question is asked. ie. I do golf from time to time but if someone is asking for advice on their game I would be the last to offer an answer."
It seems that there isn't a whole lot of uniformity in the interpretation of the hunting laws and what is "ok" in one district may not be "ok" in another.
So in addition to possibly having to have "farmland" in order to hunt on it without paying the government for the priveledge (and not just owning land not designated or used for farming) there seems to be little uniformity in the interpretation/application of the hunting laws by CO's (what is "ok" in one district may not be "ok" in another). This is ridiculous.
