I have spent many, many hours in the Billy Graham Center at Wheaton College in Wheaton, Illinois. If you have the opportunity to be in the area, I would highly recommend it. The museum on evangelism is worth the trip. I have also spent some time in the archives on the third floor of the building and recommend that also.
