Do you have a picture of the leaves? Reminds me of Showy Tick Trefoil, Desmodium canadense.

If it's a vine, then maybe Dolichos lablab.

Texasflip, I think you are correct. I took a couple pictures tonight and it appears to have a seed pod that looks very much like Dolichos lablab. It also looks like a vine, though it is hard to tell which leaves belong to which plant, I do see ones that resemble Dolichos. Thanks!
