The S&S Unlimited has a bar, the Fu-Bar, that serves corn-liquor, and opportunities to trade.
Additionally, there was a zombie-shooting contest, with grand prize a Barrett M82, along with several hundred rounds of ammunition. Second prize was a set of steak knives (possibly a reference to Glengarry Glen Ross).
