Keeping weeds out of path...
I help run a nature park and garden at an elementary school in Monroe. We have a path that runs the perimeter. The path is covered in hog fuel, which we have donated regularly free of charge. Is there a way to stifle weed growth? We are having to recover it regularly which is a great user of resources (time and physical labor).

There are a few different options for what may help your situation. What kind of budget are you working with? What weeds are prevalent?
Probably the best option to control weeds would be to use a road construction / landscaping fabric. One of the trade names for such a product is Typar. The different products are common in that they should be woven and of a black material. This will prevent weeds from coming up from the soil but will allow water to infiltrate and pass through into the soil. However, this may prove to be too expensive for your project, depending on the size and scale... Sometimes this material is discarded by road crews and can picked up by thrifty individuals.
Something else to consider, are the weeds starting and taking root in the mulch itself? It is possible that the mulch you are applying is creating a safe site for weeds to establish, is this the case? If so, there are some selective methods to try and alleviate this issue.
