Jackson Sparks was the 6 year-old boy killed in the Waukesha parade attack. His mother asked students at Jackson's school to wear baseball jerseys today. Jackson was a huge baseball fan and this is a way to honor him. This sparked a nationwide movement where people are wearing baseball jerseys today to support the Sparks family and to honor Jackson. Our friends over at @ron_jackson_insurance joined us and people across the country in #Jerseys4Jackson. #jerseysforjackson #waukesha #jacksonsparks #kalamazoo #growlers #baseball
