Its a great priviledge and honour to be a part of a few very nice conservation projects in our more and more fragile world. Even when our contribution is small it will help because a lot of kids will rememeber that particular day when we taught them about nature, taught them how to cast a fly or tie a fly, let them put eggs or fishes back into the rivers, and let them  join us while we clean rivers and beaches. For me doing all these projects, workshops and classes with so many young kids has become a big part of my retirement activities and I love it whereever and whenever I can.
