It was the summer of '69 and I was in high school in Port Huron, Mich., a small city north of Detroit where Lake Huron begins and Canada is within sight.  I still have the front page of the Port Huron Times Herald ( where later I worked two summers) from that historic day. The yellowed, fragile page is in a trunk in my attic. My memories of the lunar landing are all in black and white because I watched it on a small black and white set and there was no color in newspapers back then. It was an exciting and hopeful moment in the country, a time that even a teen with boyfriends and beaches on her mind could appreciate. Many of us have clear memories of that historic day 40 years ago, and for our cover story this weekend we talked with a number of notable Americans about theirs, including Neil Armstrong, Kareem Abdul-Jabbar, John McCain and Sally Ride. Now's your turn: Tell us in the comments section below where you were when man first walked on the moon.
