I don't think any heritage organization in the country wants to rush out and acquire federal buildings when the federal government still has a purpose for them and still wants to operate them. That's the best scenario, even for historic lighthouses—if they're still operational. Heritage groups step into the fold when there's a need. Obviously, there's going to be significant need in the country in that respect, because lighthouses are being decommissioned.
