Algonquin Lake in the Hills Firefighters weren't kidding Tuesday evening after the Algonquin Village Board approved a memorial to 9/11 victims and fallen ALFPD firefighters. They said they'd start work on it Wednesday and so they did at 7 am. By Wednesday afternoon they'd dug a 10-foot hole at the site on the north end of Riverside Park, poured a base for a two-plus-ton girder from the World Trade Center and passed two Village inspections. Still to come is backfilling, brick paving for a surrounding plaza and erecting the giant memento of the 9/11 attacks. Time is short since a dedication ceremony is planned for Sept. 11.
