Ultra-Orthodox Jews who are worried about the Internet have rented the Mets' stadium for a meeting on how to use modern technology in a religiously responsible way.
More than 40,000 ultra-Orthodox Jewish men plan to pack Citi Field for Sunday's gathering on the dangers of the Internet.
The group has also rented the nearby Arthur Ashe Stadium for the overflow crowd.
A spokesman for the event's organizers tells The New York Times that the organizers are concerned about Internet pornography.
He says they also worry that the lure of social media can limit human interaction, reading and study.
Women will not be permitted at either stadium.
However, the meeting will be broadcast live to audiences of women in schools and event halls in ultra-Orthodox neighborhoods.
