After my niece's wedding, Gayle and I had an opportunity to visit Minuteman National Historic Park in Concord, Mass. where the shots fired here between the British and Americans were heard around the world. We lived near Williamsburg, Va. before moving to Florida, so we were used to Colonial era historic sites. But this place is a national treasure and we were overwhelmed with how the National Park Service has maintained the site. We hope to visit again when we have a little more time.
