The article refers to it as “the encampment on Bach’s property.”
The article could be wrong, but that’s what’s written.
Wow... I found an article in their local Concord paper.
It’s written more clearly:

It makes clear that the encampment is on the family’s property.
And the parents are waaaaaay too accommodating.
