After a two year hiatus, the parade returns for its 84th year. Check out high school marching bands, dance groups, antique cars, fire engines, equestrian units, clowns and more while grabbing a snack from the food trucks. (And if you grew up in Montgomery County, you might recognize Master of Ceremonies Alex Tsironis, the founder of The MoCoShow, Taste MoCo and MoCoSnow.)
