Based on my expedition south for the last meet in Egg Harbor, I have realized that my view of the north/central/south lines was wrong...
Therefore... I made up a new map showing how NJ is divided.
North is where NJ is liveable for normal humans...
South is where other stuff is...
The Jersey beach is everything under exit 82 on the Parkway. That's because there's sand along the Parkway from about there south... by definition...its a beach and technically does not need to be considered as a section of NJ.
Thank you for your time and I hope you all have learned something.
