It’s been 20 years, but we haven’t forgotten. As we approach the 20th anniversary of the Sept. 11 terrorist attacks, the Richmond Times-Dispatch is asking readers to share their memories of that fateful day. Where were you? How were you affected? What changed for you? Selected submissions, which may be edited for length and clarity, will be published in our print and online editions on the 20th anniversary of 9/11. Please, share your story.
