On the eve of 20 years since the 9/11 attacks, CBS2 spoke with one man who said the wall has become a second home.

“It’s been here since 2006. I’ve been taking care of it every day,” Harry Roland told CBS2’s Kevin Rincon.

He also tries to make sure people appreciate why it’s there.

“Sometimes I just blurt it out, ‘Look at the wall, why is it there, feel it, touch it, put your hands all over it,'” he said.

Officials have said 75% of the firefighters who responded on 9/11 now have some form of illness.
