Thats all you found ? Groves are pretty good hunting areas , There's got to be more there.
But still they are very good find s . WTG
But i would do my research on the grove and find old pics of it , if you can. there is a lot more there, if there has been more then a 100 years of church part's or meeting or weddings I would be doing my home work on this place. ( Good luck to you )
