Hi. Good luck finding it. I have looked some and so far no luck. I'm pretty sure it's on Darbonne Bayou between the spillway and the south boundary of the bean field on Darbonne Refuge. With that said however, please understand that this is nothing more than an educated guess. I'm curious as to why your looking for this particular site. PM me and I will share with you what I know if your willing to do the same. Good luck and I hope you find what you seek.
