i agree 100%. Teach him to identify various trees based solely on their bark and crown structure. show him what species deer prefer and which ones they avoid until they are needed as a last resort. show him the difference in growth at the edge of a woodlot versus the growth under a mature canopy. point out the heavily used rails now may not be the same trails they use in the fall.
There is a lot to learned every time we set foot in the woods with an open mind.
