Walking Path Help!

At the Baker School, we are trying to build a tarred walking path for our families and community to use, in our efforts to promote a healthy lifestyle. The current field behind our school is a grass field used for softball games. The grass surface is wet and full of goose droppings and is messy for our kids to be walking on prior to school. So, it is our desire to build a walking path made of some material that would provide for a nice walking path for our community. The walking path would go around the outside perimeter of the softball field, so as to not interfere with the games played there in the spring. Any help or suggestions would be appreciated. You may call the Baker School at 508 398-7690 and ask for the P.E. staff.
