looks like it's okay if you can prove you own it and only hunt that property. you still have to tag game and call it in though.
Who May Hunt Without a License After Oct. 1, 2006
It is unlawful to hunt without a valid hunting license in your possession unless you are exempt from this requirement as described in this section. You are not required to possess a hunting license or stamps (except the Maryland Migratory Game Bird Stamp, the federal Migratory Bird Hunting and Conservation Stamp, and a Furbearer Permit) if you are:
[ul][*]
A resident of Maryland (and spouse) who owns property and who hunts only on that property. This also applies to the owner’s children and grandchildren if they are under the age of 16. You do not need to live on the property but must be able to prove ownership.
[*]
A person (and spouse) who: (1) holds land under lease for agricultural purposes (or a sharecropper); and (2) lives on this farmland; and (3) hunts only on this farmland. This also applies to the lessee’s children and grandchildren if they are under the age of 16.
[*]
A nonresident (and spouse) who owns a contiguous piece of farmland that is in both Virginia and Maryland may hunt on the Maryland portion of his or her property without a Maryland hunting license, if the person’s primary residence is on the Virginia portion of the property. This also applies to the owner’s children and grandchildren if they are under the age of 16.
[*]
A Maryland resident serving in the United States Armed Forces while on official leave in Maryland (whether stationed in Maryland or outside Maryland). You must possess a copy of official leave orders while hunting. See Hunters in the Armed Forces in the following text.
