I think this site is about the best to get up to date information. It is an awful feeling to drive all day over questionable roads etc to arrive at a place and find it closed or gone completely.
I try to update campgrounds here when I stay at them to help keep this board useful.
I didn't realize the Church's were still updating on their page. I saw the top listing was 2012 and thought that was it. Pretty good of them considering how long ago the book was published.
The folks behind "On the Road In" do a good job too, it is so difficult to keep all these things up to date...especially for no compensation.
