Please help identify this vine
I am from Wisconsin and I was walking between some corn fields and came across a vine that has some interesting pods. If it is something that will look good in the garden, I am ready to save the seeds.
The dried pods look a little like gomphrina but are about four times as large. They are beige when they dry out but green with spikes when they begin to make seeds. The seeds almost look like watermelon seeds and are inside the pod that opens like a moonflower/datura. There is also a beige mesh like structure inside the pod when it deposits its seeds.
I have some pictures but am not sure how to attach them.
