Today marks a dark moment in American history. The attacks of Sept. 11 affected Main Street and Wall Street in unprecedented ways. Whether you worked on Wall Street - only blocks away from Ground Zero - or lived on Main Street, this day eight years ago has become a part of your history as well as ours.

We at MainStreet thought it was important to give our readers a space to contribute their memories and thoughts about the terrorist attacks.

To honor the memory of those we lost today, please share your stories from Sept. 11, 2001 in the comments thread below. The staffers at MainStreet will be contributing their memories as well.
