The next photo is of a terribly invasive vine that has just taken over this year. It is all along the road I live on, its climbing my trees, getting tangled in my beds and making a big mess! What is it and how do I eradicate it?

The second looks to be a cucurbit and I think I see a spiny fruit in there somewhere, so it could be wild cucumber. Doesn't grow in my area, so I've never seen it, however by the look of the leaves and vines, I would think Round-up or 2,4-D would control it, though repeated applications would probably be necessary to eliminate it. I'm sure hacking it back would work, although to kill it you would probably have to find where it is coming out of the ground and hack it off just below the surface and repeat this process everytime it starts sending up new shoots.

Your photo is not clear on my monitor. Read all of the information toward the bottom. It is a very important plant.
