When you re-visit places you knew from your past usually many things change. Sometimes so much that you have a hard time recognizing the place you thought you knew. One reassuring constant in this rapid changing world though are fully grown trees. They usually are preserved no matter what construction is going on. While I was driving around yesterday in the bay area I marveled at the many changes since I left. And more than once I recognized old trees that where there a decade ago and probably will still be there twenty years from now. Reassuring.
