The response was not exactly a snappy salute. Facing a driving rain, two counter-protesters who compared the activists to Saddam Hussein and grim-faced military policemen ordering them to cease and desist, the group was forced to turn around about 30 yards from the entrance to the Edgewood Area of Aberdeen Proving Ground.
In a caravan of cars and minivans, they met at a Texaco station near the base before heading down a two-lane road leading to the facility. Two men along the road yelled at them through bullhorns and held up signs such as "Why aren't you in Iraq?" and "We gave peace a chance; we got 9/11."
