Marching bands, clowns, and lots of floats... it's all happening today as the Port Huron Rotary Club International Day Parade steps off to unofficially start up all the Mackinac race activities this week, including the Blue Water Fest. Parade Co-chair John Adair says there'll be plenty of music for the parade as both Port Huron school district high school bands will again be represented as will a few well known out of area groups. The theme of the parade this year is The Circus, and Wayne State's Troy Burrell, who's a Port Huron native and has been chosen as the grand marshal. The Big Red Marching Machine will be the first band while a color guard starts things off thanks to a veterans organization. It all starts at 6:30pm at Huron and Glenwood, then continues south through the downtown business district. It turns east from Military onto Oak Street, and then disbands at Desmond Landing. In keeping with tradition many parade lovers set up lawn chairs as early as yesterday afternoon to claim prime locations for watching the parade.
