It is organized every year by Vermont Overland. Peter Vullers is the owner of it, tickets go on sale 1/1/2020 in the evening and usually gone in 2 days. It is a worthy event overall, more driving than other stuff, no vendors besides food trucks. The trails are just VT ancient roads (colonial footpaths pretty much) that the state forces to remain open regardless of ownership. We only encounter one bridge out on a trail and the land owner let us drive through their front lawn pretty much. Good people. This is our second year going, camping is all over his property, ranging from jungle trails to open pasture, very cool.
You know the NE, the soil is black and when it rains its just deep mud!
