Later: I got there just on time. I got the herbs.
Trucks were honking at me. I pulled off the main drag, and saw that my trunk was open. So the herb sale people put the herbs I'd gotten in the trunk, but didn't close the trunk.
I stopped at a farm that advertised that they had a store, and got a couple of little bars of goatmilk soap.
I was exhausted when I got home. I put the flat of plants on the porch, and watered them in the late afternoon/early evening. It was very windy, and supposed to be rather cold at night, so I brought in the scented geraniums, heliotropes, and basil. The chives and Greek oregano got through the night outside just fine. I put the scented geraniums back out on Wednesday morning.
