What Sidedish to make for BBQ

[CollinEstes]

Got a huge family/friends annual BBQ tommorow out in the sticks. (The people that run it kill a whole cow for the thing each year). Anyways I am planning on bring a side dish of sometype and don't want to bring the usual stuff (deviled eggs, potato salad, baked beans, etc...) becuase everyone else brings those.

So anybody got any suggestions on what I should make, and possible what beer I should bring for myself.
