Although the kids will grow and eventually leave to live their own lives, when you allow them to experience things like this on their own terms, they tend to develop a connection to the time, place events and people involved.

I don't have kids, but all of my nieces and nephews have been fishing with me.
Some still like it, some have moved on to other hobbies, and all still remember the outings.

Very good article!
