Kind of funny that they donate money to install synthetic field turf "to help improve the quality and safety of fields" but won't put it in Soldier Field because, according to their own "research", it isn't as safe as grass.

Douglas Park
In March, the NFL and LISC announced that the Chicago Parks Foundation will install a synthetic turf field at Douglas Park in the North Lawndale community due in part to a $250,000 grant from the Chicago Bears through the National Football League Foundation Grassroots Program. Douglas Park is the home field for the Academy for Urban School Leadership's tackle football program, which is supported through Bears Care grants, along with the football programs at Johnson School of Excellence and Collins Academy High School. LISC identifies local, nonprofit, community-based agencies that have an interest in building or refurbishing football fields in schools and neighborhood parks. Through the program, local agencies are provided with the necessary financing and technical assistance to improve the quality and safety of fields in their communities. The agencies oversee the construction, maintenance and programming of the fields.
