That is bad news, because it's likely symbolic of where other courses stand (and not just the ones Garland mentioned ... I think Rock Creek is on a lot more solid footing than some others).
The amazing thing is that Black Rock was "doubling down" and getting ready to open a second 18 holes (by Tom Weiskopf). Did they get it open before it closed?

Spending a lot of money was one side of the equation. Not recovering the anticipated amounts through lot sales are the other side. Second-home golf communities are not in the sweet spot right now ... and like banks, many of them are highly leveraged (by banks!).
