We have a beautiful, natural (well, mostly natural) pond just off the deck at the side of our house. I spend a lot of time out by the pond in the summer. I try to make sure I get out to it between each of my calls, in fact. It helps to center me before each call.
I love it. I love that it is a natural and abundant ecosystem. I love that all sorts of plants and animals make it home. I especially love the frogs.
We have mostly green frogs (Rana clamitans), but also have leopard frogs, spring peepers, wood frogs and toads.
