When my 35-yr-old son was about ten, we camped at Patrick's Point State Park in Northern California. As we walked along an agate beach, we saw a whale in the water, about twenty-five yards out. As we walked along the beach, it seemed to be aware of us, swimming alongside us for a good fifteen minutes.
Another time, we rented a house not far from Mendocino, California. As my son and I walked along a cliff over a secluded beach in the eraly evening, we saw five or six deer playing in the surf.
I don't think I'll ever forget those two walks I had with my son.
