I traverse all of Shelby Farms/Wolf River regularly. I've notified management several times that the primary reason trash accumulates is because of their total failure to provide trash bins at trailheads. But they ignore me. Hikers have no place to put their trash so they throw it on the ground. I will PERSONALLY clean up all of Shelby Farms over two months once management provides trash receptacles at trailheads (except for the prison area) The huge volume of refuse behind the prison is a disgrace and harms the soil and wildlife daily. Prison administration needs to get a work detail out back with some trucks, load up all the dumpings and haul it all out of there.
