History rolled through the streets of downtown Bangor Sunday. A vintage auto parade marked the last of three days of activities designed to remember the Brady Gang shootout, 72 years ago.About a dozen classic cars wound their way along Water Street, Main Street and then against the normal flow on traffic on Central Street, since in 1937, Central Street was a two-way road. The cars passed right by the former sight of Dakin’s Sporting Goods, where two of Al Brady’s gang bought guns. It was also there where clerk Louis LaCrosse first became suspicious of the men, which lead to a tip to the FBI.In honor of that, LaCrosse’s nephew, Peter LaCrosse was the Grand Marshall of today’s parade.Peter LaCrosse says remember the Brady Gang in Bangor is important.”Oh I think it’s one of the major events of Bangor. They were number one, public enemy number one in 1937. The last one to be shot, after that the war came and that was really the end of an era. Dillinger was shot and most of the criminals – Al Capone was in jail. So it has a history of this was one of the last ones they really wanted to get ahold of.”Mayor Gerry Palmer also declared Sunday Louis LaCrosse day. His nephew says he’ll pass on the special plaque he received for that to LaCrosse’s wife.The weekend’s activities were also part of the celebration marking the 175th birthday of Bangor.
