DULUTH, MN (KDAL) - A new trail that will make it easier for Lincoln Park Middle School students to walk to school will be built by community volunteers on Saturday.  The gravel footpath will connect the neighborhood just east of the school with the existing paved walkway that the school district constructed.  On Friday students at the school will work with the City Trails Coordinator to get the project started by clearing brush and moving gravel onto the pathway.  Those who wish to volunteer on Saturday can register by calling 730-4334.  All equipment needed will be provided.
