It sounds pretty typical for public land. Unless you are willing to work your ass off scouting and going deep or into undesirable places (think of places you would least like to drag a deer out from and start there) you will have very little luck seeing anything worth killing. I'm a bit surprised you haven't gotten lucky and seen more does, but some people just miss deer that walk right in front of them, so I bet you've had more deer than 3 cross near you, they can be pretty darn sneaky.

One year I bowhunted about 25 sits on the local wma all during the week so not much pressure, and scouted a good bit after nearly every hunt. I was determined. Found good buck sign, even saw a few in the flesh while scouting.

That whole year I had an opportunity one time at a legal buck and it wasn't even a good opportunity, so really it's like I never had a chance. Saw tons of deer, but getting something within bow range that's legal and ready to die is extremely hard on public land.
