In a photo from Thursday, May 15, 2014, Andy Williams loads trees on a flathead at the Hantz Farms in Detroit. A mass tree-planting effort is planned for Saturday, May 17, as part of a large-scale project by a company that wants to put vacant Detroit land to agricultural use. A daylong event is planned by John Hantz where volunteers will help plant 15,000 young maple and oak trees on 50 acres of land where crews have been clearing blighted properties for the project.
