Thanks, Dr. Veith!
A church in Superior, Wisconsin is sponsoring a Bible-reading marathon.
So it only takes 72 hours to read the whole thing! The 17th century Anglican community of Little Gidding would sometimes do Psalms marathons and the like. This would be a good activity for youth groups (they could get people to contribute for each hour they read) and whole congregations (I've been in churches that have prayer vigils–why not Bible reading vigils?).
