This came up a few months ago for me. Talked fairly seriously about going over to do a specific story, in and out in probably two or three weeks. Would have spent most of my working time in the Green Zone, but would have slept (or, more probably, "slept") outside of it. Also would have had to have done the sprint from the airport to relative safety, which apparently is not a very nice introduction to Iraq.
I'm married, and at that point, our son was three months old. I talked to my wife and my parents about it, and really thought hard about it. And I decided that I would go -- for the story and what it might do for my career, and also for the life experience.
In the end, the magazine decided against it.
To be honest, I think I would have been scared every minute I was there. And if I had ended up wounded, I would have regretted going for the rest of my life; had I been killed, my wife would have for the rest of hers (although she'd be rich from insurance, so maybe not that much).
Still, I think about it now, and I kind of regret that it didn't happen.
