You should find a bar that is showing the Mets game at 1:30 today, and watch the Mets clinch their division. Sure, it might be kind of hard in Georgia, since they're probably still mourining the Braves.

But the third time's the charm, right?
Failing that, staying at home is cheaper. But if you go out, find a place that has Sam Adams on tap.
