When does the camp out start?

Grieved father Ronald Griffin writes in today's Opinion Journal:

I lost a son in Iraq and Cindy Sheehan does not speak for me.

I grieve with Mrs. Sheehan, for all too well I know the full measure of the agony she is forever going to endure. I honor her son for his service and sacrifice. However, I abhor all that she represents and those who would cast her as the symbol for parents of our fallen soldiers.

When will the media circus begin?
