Manny, I see the island is covered with invasive Australian Pine, or Brazilian oak, or any number of other names, since Australian pine is a misnomer, as Australia has no native pines, just imports for timber, and paper.  But have you ever attempted a quickie bow out of it?  Steve Parnell came over to Eddies, last week, and he had one he had made out of it, and I was impressed, enough, that I just might go cut some.  I always thought it too brittle.  It is supposed to be in the Hickory family, as I was once told a long time ago.
I know it will rot pretty quickly in the outdoors.  But it was just a sapling bow, and very snappy.
