wild grapes- blessing or curse? [View all]

our lot has an old wild grape that had pretty much eaten about 50' of fence. we did hack it back this winter, but didn't really make up our mind about whether to really root it out or to try to contain it. it isn't really in the way or anything.
there is still a good bit of it there, and yesterday DH came out to find 5 greek ladies picking leaves. he assured them that it was fine. they sadly noted that there used to be a lot more. i think the ladies will survive if we take it out, as it is common around here.
i, personally, have never used the leaves for anything, but i suppose i could learn a few recipes. i don't know what, if anything, the grapes are good for. i tried a couple of the dried ones that were still on the vines. they are tasty, and extremely purple. but they are as much seed as grape.
i could always feed this stuff to the chickens.

so, anybody have a strong opinion about wild grapes?
