Derik;
That's a papaya tree it is leaning against, the hanging thing is a Chayote, a mild squash from Central America. Both of the bows have a flat belly and are oval shaped.
Adam, I'm thinking about bracing it but I'm not sure if the string will hold up. It's very dry. I made a string and shot my other one, it's a wrist slapper with the low brace height they are supposed to have used.
