Gwen is a bit swamped today, so bear with me as I try to fill her shoes. Here's (briefly) what's on tap for the show today:

In the first hour, Generaton Kill, a new mini-series by David Simon and Ed Burns (of Wire fame) that tells the story of the invasion of Iraq, through the eyes of the men of the First Marine Reconnaissance Battalion.
We'll spend a few minutes at the end of the hour reading from your letters, and revisiting the flooded areas of the Midwest.

In the second hour, we'll talk about the situation in Zimbabwe and ask: What should we do about it? Given the West's history of colonialism, how far can Western countries go to intervene?
Before we sign off today, we'll talk with Barbara Ehrenreich about her latest book, "This Land is Their Land." You can tell from the title she feels the U.S. is full of economic inequalities, we'll ask her what the answer is to the problems she sees.
