This is what I like to hear. Get those kids outdoors and observing nature.
I met someone the other day who bought my little children's book on foraging. She said she read it with her boys and the immediately asked her to take them out to forage and they did a little more research and found red bud pods that were brand new. They brought them in and cooked them 3 different ways as an experiment. That is exactly the kind of response that I was looking for. That made me so happy! :-)
