So let's say bring:
your Beverages of choice
something shareable to snack on if you can,
some cash for the Taco Truck Run, and
a toy for the Toys For Tots program if you're willing to do so...
I'll ride to the taco truck with you, but I am no longer allowed to get drunk and need a ride home... unless you want to stop at costco on the way to my house.
