there are a few kids derbies that can use volunteers. the one on Lower Range, and the kids portion of Crystal Lake are two that come to mind. just stay tuned on here and you'll find some calls for volunteers. if you want to really go above and beyond, get involved with Hooked on Fishing, you can become a "certified instructor" and help out at certain outings that they do.
