It seems this native plant is sprouting in many places right now.

Thank you for including the image with your inquiry. It has the detail and plant parts needed to identify the vine. Your mystery plant is wild cucumber, also called manroot, Marah oreganus. The common name of “cucumber” is misleading because the fruit isn’t at all like an edible cucumber. It is often dried and used in dry flower arrangements. The root can be extremely large; I’ve seen several exceeding 20 pounds.

See https://en.wikipedia.org/wiki/Marah_oreganus and http://www.ipm.ucdavis.edu/PMG/WEEDS/wild_cucumber.html.
