Allow me to make a general observation here, Bruce - I am really enjoying this quiz thread! I don't know much about ponds yet, being brand new to ownership, but this has been a blast and I've thoroughly enjoyed the mental exercise of really thinking about the questions and learning a lot from the answers being provided. It's giving me a lot of great idea of things to learn about my own ponds as I enter into spring and start really trying to dig into what makes them tick and learn about the seasonal changes and "moods" they take on.
Thanks for the great thread!
