How do you address two or more people, as in "Are ______ going to the store?" or "Where are ______ from?"

This question didn't work out quite as I expected. There was a huge write-in of 'you guys' which wasn't exactly what I wanted. It is quite apparent, though, that 'y'all' is a southern thing. And if you look real close, you may be able to see that they say 'yins' in Pittsburgh.
