Emotions ran high among the crowd of demonstrators at 16th & Broadway who gathered on Saturday afternoon to mark the 4th anniversary of the invasion and occupation of Iraq. They included a mixture of anger, sadness, determination and optimism. Comic relief was provided by a young man in a Bush mask and carrying a gas can. Passing motorists were overwhelmingly supportive, as evidenced by their horns, thumbs ups, peace signs and shouts of support.
