What acreage is devoted to truck gardening in Indiana? If the drought in California persists for many years, could a substantial portion of that vegetable production move to Indiana?

How easy do you think it would be for farmers to shift from grain production to vegetable production? There truly are huge differences. Expansion of our current vegetable crop growers might be the first step. If the market will bear.
Second question: What do you want us to replace from California? We are a seasonal state. Three months we are pretty much out of commission even for cool weather crops. High tunnels can only cover so much ground. However, if the economics are there, farming can and will change.
