Rochester is a heavy agricultural district known for corn, melons, cabbage, apples and cherries. We live on the edge of a huge apple orchard and our son used to get money in summers working in the orchard picking fruit.
No need to worry about inexpensive carbs! We have plenty here. Fruit and vegetable stands about every mile with some of the finest corn you can eat. And, thank God, no drought here. Just some erratic rain.
Good luck. I grew up in Rochester a few blocks from the Eastman house. I still miss the city at times, even though I'm very happy where I'm at. There's just something that feels "right" about Rochester to me (but it's not the lack of sun in the winter).
