We visit in summer, but only briefly to avoid the "skeeters." We visit in fall, Fisher shoveling in piles of fallen leaves. We visit in winter, when the ground and water are frozen, walk out onto the stream, and listen to them marvel.
We return in the spring, to see green buds appearing, animals returning, water once again flowing.
We love our little stream, and what I love is that when the kids are grown and remembering childhood, it will be a special place for them. Nothing I really tried to do, nothing I had to force, just this simple little spot near our house that we visited all the time, that easily forced itself into their hearts.
