Oh man, the FROGS!! Yes, it's why we bought the property - there were frogs and a lake right at the bottom (well, a big clear dam more like) full of lilypads and frogs and we were like, yep, if the frogs like it, so do we. And that was a good punt as the soil is good and all we had to do is add more organic matter and things would grow well. They do give me a fright when I uncover them though!
