So looking at those lists I see that Maryland has

Limited
Cove Point (also LL)
Craighill Rear
►Piney Point (also LL)
* Turkey Point (also LL)

Open
Drum Point (also LL)
Hooper Strait (also LL)
Seven Foot Knoll (also LL)
Thomas Point (also LL)

and only Little Lights (and it would be easier if these were alphabetical) for

Sharps Island
Baltimore
Concord
Craighill Lower
Sandy Point
Fort Washington
Point Lookout (but not the new paint job)

I haven't seen Fort Washington or Concord because I haven't been that far north or Hooper Strait.

The ones that I've seen that aren't in there are Hooper Island, Lazaretto (which is a replica), Fort Carroll, Solomon's Lump, Jane's (or James) Island, Cedar Point [remains], and Point No Point. I've also seen a model of Blackistone Light.

It would seem to me to be more commercially viable to do lighthouses that are still there to be looked at, but of that group that hasn't been done AT ALL (so no duplicates), I'd like to see Fort Carroll, Cedar Point and either Point No Point or Blackistone.
