The Island restrictions
Just rewatched episode 6 season 5. At the beginning where Ms Hawkins is talking the our losties we get to see the map of the world on the floor with various markings on it from the pendulum. If you look closely and/or pause when the map is shown at its biggest, you will notice that there is a marking (star shape) which looks to be over mainland America. I have read a few theories on here and other sites which mention the special places on the planet. Someone did post a picture of those places recently but i havent the time to go look for it. Well the location of that star doesn’t look that far off the pictures location of these special places.
