Planning notes for a Labor Day party

End of summer means people are ready to indulge one last time.
Weather can vary - have backup plans for rain.
Pool parties need drinks near the pool AND inside.

Similar to 4th of July but slightly higher consumption as people celebrate the end of summer. The table above sizes the bar, and beer carries most of it.
