Bikepacking is essentially cycle touring off road with camping in mind.
There is a strong emphasis on avoiding roads with cars. In a rural state, like Vermont, this is achieved fairly easily. We have more dirt roads than paved roads and an abundance of Class IV roads that connect us to the outdoors.
A Vermont rider, Calvin Decker who has done some very impressive rides, describes this growing segment of cycling very well. You can read about it here on the North Atlantic Dirt blog.
