You said -- "I don't think the Rapture will happen until the Tribulation is well under way."
Well, I do know that there are several positions that Christians take in that matter. I -- for one -- take it as pre-Trib. From what I've studied and read, it just doesn't make sense any other way.
As it stands, today, there are four positions. One of those came in the last 20 or so years. I've looked at them, and pre-trib has it all together from what I can see. There are ample materials out there on that position, and I'm sure you could find them. Thomas Ice provides a nice web site on that position, from annual conferences that they've had, you could go to David Hocking for another. Or you could try John F. Walvoord. Arnold Fruchtenbaum is another (and it goes on and on).

I used to be pre-trib, until I realized that we are warned to keep an eye out for the abomination of desolation in the temple.
