A memory from September 11, 1970

As a young boy my elders gave me a lesson on why not vandalize a tree.

I eventually learned about ecology, inner tidal zones, and naturalism.

I did a lot of tree planting and forest fire fighting as a young man.

I spend a lot of time outdoors: walking, hiking and biking.

I try to recycle, recover and reuse.

All these activities are still practiced across the country.
