Happy Birthday, Pres. Lincoln!
While you're celebrating Darwin's birthday, don't forget to have a piece of cake for Abraham Lincoln's 200th birthday. What a day Feb 12, 1809 was! Though one was in Kentucky and the other in England, two extremely significant historical figures were born on the same day.
Here's a museum I can personally recommend as well: Lincoln's museum in Springfield, Illinois. To celebrate Lincoln's birthday, you can watch school children or the Illinois basketball team (let by Michael Jordan's son) recite the Gettysburg address on the museum's YouTube page.
