Ellen,
OK, I tried again.
Went to Good Sam directory. Used the map search feature. Selected Oregon, since I am very familiar with campgrounds in the sate.
Map appeared and only Good Sam parks appear - no state parks (many on the coast), no USFS, no county parks, no other private parks, etc. appear on the map.
However, to test the feature, I click near or on a Good Sam park and other listings did appear. Only after digging deeper did other listings appear - it was not obvious.
The point remains - the old Woodall's online directory would list all campgrounds from closest to fartherest from a chosen location.
Am I pleased with the Good Sam directory - no. But perhaps there is a way to gain some additional benefit from it.
