Lineup entrance will be at 8th and Dayton in Kennewick. Come in by way of 10th avenue, as most of the other streets in the area will be blocked off. Judging of entries will be at 8:15am, so everyone needs to be in place and ready by 8:00am for judging. The parade begins at 10:00am. Hope to see you there and have fun!
