the field
Saturday. I spent three Saturdays walking north of San Antonio with the Garmin, along dirt roads and between houses, chasing the zero.
Today I found where the line crosses a road: a dirt track with a cornfield on one side. The true equator runs straight through the corn. 0°00'00.0", if I stand between the fourth and fifth rows.
There's a little house at the end of the field with a blue door. Next week I knock.
