I suppose things change and the population has expanded so that arranged tours are logistically easier to handle.
I long for the old days and when I toured the WH, President Grant agreed with me.
No, you could still do that up until 9/11. After the terror attacks, they shut down the White house to all but scheduled tours, and it’s hard to get a tour at all.
I really wish I had gone to the White House when it was open to everybody. I don’t have $50,000 to donate to get a “tour”.
Of course, I wish I had gone to the top of the World Trade Center towers before they were knocked over as well.
Amazing all the things you never do when it’s easy to do.
