My family has been involved in the peace movement, and in the rice project. I just wanted to provide you with a link to an interesting article that was posted on the website of the group that we're part of locally.
Go ahead and read the whole thing - it give you ideas on other places to send rice, like your local senator or representative's office.

Unfortunately, I'm not sure of the author... I will try to find out who the letter is from.
