There are many different sides of every country that you visit. You can take the city lovers route and discover all of that, or you can take to the country and get in touch with how people used to live before cities and the many conveniences that we have today.
The farm life in the DR is like that of the farm life in many places of the world. There is seldom electricity, the water comes from the rivers and you live off of the land. You get what you give.
From my experience this creates an authentic person. Not changed by the outside world and connected completely to nature, if you're looking to see some true culture you go to the mountains, rivers and deserted places where few people live.
