David,
JB was part of our regular rotation in the late 80's/early 90's. A very enjoyable and playable golf course.
They redid some holes maybe 25 years ago, I think. Nos. 1,2,3,18 were changed slightly if I recall.
A friend in 'Squan played it within the last 2 years and says it remains among his favorite-non private-courses in the area.
Google Earth time lapse mode will show the course and the changes very well.
