This location for the camp is correct.
However if one goes to this retreat
website:

http://www.camprecovery.org/about.html

and look at the map on that page, It shows the pointer 1.5 miles past the location of the camp?! What is causing this?
But, if you click on View Larger Map then it shows the location correctly. But, this is on Google Maps. So, when the map is small, the location is wrong, but large its correct. It appears that there are two mapping services at play.
