In 1943, when Winston Churchill was on a tour of the Maryland countryside, he recited all of the verses to "Barbara Frietchie." He had memorized that and many other poems years earlier while a young army officer stationed in remote areas.
I've decided to have a personal revival of that practice, starting with some easy stuff and then working upwards. There are a few poems that I memorized in elementary school that are still with me.
Let's hear it for Longfellow!
