Teachers and supporters of education were standing an an overpass which allowed them to flash their signs and wave to drivers as they passed below. Teachers from throughout the state converged at the Capitol to bring their concerns about education funding to the attention of legislators and state officials during the first day of a statewide public schools teacher walkout on Monday, April 2, 2018.
