Can anyone identify this vine? It's currently growing on the ground, as it has nothing to climb, and it's sending out long shoots in several directions. I'm in zone 7a if that helps at all.

I believe this is Virginia Creeper (Parthenocissus quinqefolia) on the basis of the five serrated leaves that have holes in the leaves that are the typical signs of being eaten by the grape flea beetle.
This plant is a robust climber that is not be treated lightly. It is a member of the grape family and around this time of the year you can often find the small pea sized purple berries. It turns a vibrant red and is very attractive at this time of the year.
It has been known to cover houses and was described by Trevor Cole, former curator of the Arboretum in Ottawa where I live as the only plant he knew that could be planted upside down and still live.
This is a plant to place far away from delicate plants and structures as it will overgrow them. I have one that is fighting it out with my cedar hedge and Explorer rose bush. So far it has not ripped out the chain link fence it is growing on....
I think it is Virginia Creeper, a pretty agressive weed (in my opinion). See http://en.wikipedia.org/wiki/Virginia_creeper
