I think we will find that 19 families on 97 acres will not leave the space they need for farming, infrastructure, sewage treatment, water, and garbage. then they need roads, heavy equipment for maintenance, skilled farmers, skilled engineers, and almost all of the trades. Pretty much everything will have to come from the outside. Then of course, there is the cost of all of the infrastructure and building. I hope these people have lots of money. Their goal is nice, but their probability of success is slim.
AND ... the soil there is VERY marginal, and summer rains can be quite fickle there.
