What was your green epiphany? "In 1979, when there were hostages taken in Iran, and oil price increases, and gas lines and lots of discussion on foreign oil. "
A green hero: "Today it would have to be Al Gore, but I also like Amory Lovins."
A sustainability practice you recently added: "We just bought our second Prius."
