pdq: Simple. Redwood is "green" when it leaves sticky sap on my customers pants, as I found out the hard way! Cute question!

Sorcha: your story reminded me of an opportunity I missed years ago. I was giving guitar lessons to the daughter of an wonderful painter. She offered to trade me guitar lessons for her daughter for "color lessons" from her. At the time, we needed the guitar lesson money more than I needed color awareness, but I've always wondered what changes that would have brought to my life. Bob
