While in college, Sonya and I rode a bus to Columbus to attend a Billy Graham crusade. ( I think the main lure there was a free bus ride off of campus, but I'm sure that we also wanted to hear Billy Graham speak).
I wish I could say that I remember lots of profound things from it, or that it changed my life. One of the few things I remember is drawing faces on the people in the program. I know, so immature! I was in college, what do you expect?
There was one good thing from that trip. I got this book. It is an excellent reference book for Christians.
