Here's a you tube video, Chuck Missler on the Rapture. It's part 3 of 12, but you can find them all on youtube.
interesting what he says around 8 minutes about the U.S. having the audacity to think we won't suffer and persecution as the rest of the church has experienced since Jesus left. I think for myself, that is the biggest hurdle I have getting over is that how are we the worthy ones to escape? so, we aren't promised no persecution, just no wrath of God.
