Horsenettle?

I'm no bottanist, but some internet digging convinces me this is horse-nettle. And apparently it is rather poisonous. I though these berries were pretty cool, though.

I generally hate my attempts at macro / close-up, I think I'm just not patient enough.  But this turned out ok.  Enough dof to have the subject in focus, but decent blur on the background.  Still, the tops of the stems could be crisper...
