This time of year (arguably the nicest time of year in Michigan), I go carfree foraging a couple times a week. For example, on Monday I rode my bike out a few miles into the country and found a farmhouse with a produce stand in front of it. I bought a few pounds of tomatoes, a few ears of corn and a bouquet of fresh basil. I paid by "honor system," then I loaded them all into my backpack and headed home. Within a couple hours the tomatoes had been diced and cooked in olive oil with the basil, and the corn was lightly steamed. I grilled a tuna steak and poured some tomato sauce over it and the corn. That was one of the best meals of the year! Some of the tomato sauce went into tupperware containers to be frozen and enjoyed this coming winter.
Besides the freshness, the other good thing was that no fossil fuel was used in the production or transport of my food.
