Smiley did a wonderful post on the Hail Mary, by St. Louis de Montefort here. There are so many ways to honor our Blessed Mother, and this Mary Month of May is a good time to reflect on how much or little we do every day to honor the one who brought the Salvation of the world to us. The beautiful Hail Mary, well said, is probably the simplest and best way; anyone can say it, and it's even appropriate for non-Catholics, as it is Biblical in text.
I encourage the wearing of the brown scapular, daily Rosary, and the Little Office of the Blessed Virgin. I usually do Prime and Compline from the Little Office, sometimes one or two of the other Hours.
