You can’t understand a watershed until you think in its numbers.
Case in point is the rain barrel.
I’ve been walking all over Belgium with the Old Florida way of thinking stuck in my head:
Each barrel holds 42.5 gallons … right?
But from a translational standpoint, I might as well be speaking Greek, or Chinese … or any other language you don’t know (for me it’s all of them except English):
Nobody knows what a gallon is in Belgium.
The standard unit of measurement is liters.
Each rain barrel holds 161 of them …
But they have to be full!
