We saw these strange round balls along the side of a side road in East Windsor Connecticut. They were hard and bumpy and most were about the size of baseballs - some like softballs.

Sadly my digital camera croaked, so here is a scan from my scanner - pretty good 3D picture for a flatbed.

It took Martha a while in the books to find out they were from the Osage Orange tree. The internet was little help until I knew the name - then there were a lot of neat references to this strange tree. Google and even Jeeves search engines just didn't know what to suggest when my search was "I found these weird bumpy green things off a tree" If you want info about these, here is one link.
