In MD the public ground gets more restrictive the closer you get to Baltimore- depending on the area it can be as simple as getting a permit you print and carry to certain places near Sykesville and on the eastern shore that you have to get a permit for then they only let so many people on per day- so you drive there and if the roster book is full, you just wasted your morning or afternoon. Others have call-in registration. BUT, not all public lands in MD are like that. The ones west of Frederick are all just like PAs SGLs or SFs, show up, park, hunt.
MD tracts of public land are not well publicized or marked. You have to do your research.
Private land in MD- similar to PA. No way to tell how productive a private land spot anywhwere in MD will be until you scout/hunt it. Could be loaded w/deer, could be fairly lame.
I got permission to bowhunt a farm in Washington County MD a few years back without even looking at the place. Got there and it was all fields, very few trees for a stand. Saw lots of deer in the dark, driving in/out, never saw one in the daylight.
I have a lease in Frederick County, 150 acres mixed fields/woods. Have taken 2 nice buck off it in archery, but after 2 years of scratching my head trying to figure the place out. Found out during daylight hours at least they don't like the woods dropping acorns by the bucket or the swamp, they LOVE the thick brush along the road!
Regardless, any private land spot in MD is worth checking out, bow, rifle or ML. Out of state license is relatively cheap and no hassle w/mail in doe tags or anything like that. In the region east of Hagerstown it's basically whack 'em and stack 'em. You do need a $10 bonus buck tag and have to harvest 2 doe before you can shoot a second buck. Towards Baltimore it's unlimited doe harvest, further west its 30 doe/year until you get into far western MD, then I believe it's 1 buck and 1 doe (I don't hunt out there so am not too familiar w/regs in that part of MD).
Ask if he'll let you hunt the early Muzzleloader season- in MD the 1st 3 days you can shoot buck or doe!
Best of Luck!
ps- I have 1 private land spot in Annapolis, a 2 acre parcel. Next 4 acre parcel is owned by the owners cousin. Property on the other side is maybe 30 acres and you can't see the house, so for archery no safety zone issues with the "far neighbor" (owner and his cousin said I can sit on their deck and shoot deer if I want to). All of this backs up to a several hundred acre nature preserve that's fenced with no public access. So deer wander in/out of the development by the score from the woods.
Problem- most days I work from home, and during archery I often turn the phone off and "disappear" for a few hours. Almost impossible to hunt weekends w/2 small kids and all their activities. It's always 3-4 hour "surgical strikes" during the week. And the guy who owns the place in Annapolis is my boss.... It would be awkward to be driving out of his driveway in camo as he's coming home from the office
