Okay. I'll stop you here because I have another question.
We all have our reasons for considering a site of historic significance, whether the site is a post office, museum, lighthouse, wharf or any other location. You've designated about 2,000 federal buildings and historic sites. These places have now been listed.
In an ideal world, we would protect everything. However, we must face the facts. It's impossible.
How do you establish an order of priority?
