Last fall when I arrived here in Florida a neighbor had a huge vine growing
over her stoop and front entrance. She didn't know what it was and pulled
it out. It had obviously grown there over the summer.

It had some baseball sized fruits, brown with sort of spots. I got one to
take north with me but am wondering if it could be any relation to kudzu. I
would hate to introduce a pest up there but it grew so fast I could use it
if it is controllable.
