New York City Exclusion Zone
In the Legion of Lawndale Heroes universe, the New York City Exclusion Zone is an area surrounding the City of New York (out to about sixty miles) where the provisions of the Bowman Acts are not generally enforced by the United States Government. The full reasoning for this has never been fully disclosed; however, one reason for this is that it would interfere with the longstanding rules of diplomatic immunity and the soverign nature of diplomatic areas being considered foreign soil. Moreover, even though a number of the nations within are signatories to the Bowman Acts, the United Nations, as a legislative body, does not recognize them.
The effect of the Zone has been the development of an underground metahuman culture that has always existed within the city itself, but expanded greatly upon the passage of the Acts and the announcement (through secret channels) of the Zone's creation. This has also led to the viewing of New York City as a 'safe haven' for people with those abilities, and many metahumans (and their families)have begun new lives and careers in the area.
Brooklyn, in particular, has become an area where metahumans congregate for business and pleasureful pursuits. (Coney Island, for many years in decline, has begun a resurgence so profound that many businesses in the area, including the various amusement parks, have been able to plan major upgrades and expansions on their various holdings because of the influx of metahuman visitors from around the world and alien visitors from off-world).
