At the memorial site, there was also a small building where visitors could sign a guestbook.

Within a month of its opening, visitors from all 48 states had signed the guest book.

A reminder that this is the real thing comes from staff members, who ask visitors to sign a liability release and pay the $7 admission.

As of May 16, 107,000 visitors to the church had signed cards saying they had been saved.

By the afternoon of November 10, over 1200 unique visitors had signed the petition.

Today, this would be where visitors sign the guest book.

Nasseri also asks most visitors to sign his journal.

In fact, one visitor signed the guest book, "Please, can I live here?"

The book allows visitors to sign in, see who has been there and from where they have traveled.

Outside, visitors can sign a petition requesting more research and development.
