There's an archery range posted on the premises at Fort Meade, though I've never used it. Anne Arundel Archers is the closest club - about 20 minutes away. It's a field archery club with a nice course walking through the woods. The first 3 or four target butts are open to the public for free, but club dues are really reasonable, something like $55/yr.
As for 3d, I haven't found any blind with a good 3d course with 30 minutes. Heart of Maryland Bowhunters has one, as does Baltimore Bowmen. Both are about an hour or so from Meade.
