Vernon Square is a district in Washington D.C. Entering the district will pick up the Ranger Emergency Frequency on your Pip-Boy, this leads to the Reilly's Rangers Quest. The district is a sweet spot for Super Mutants, likely due to the high levels of Radiation left from the wrecked Delta IX rocket in the center of the Square. Getting too close to the Delta rocket can give you up to 43 Rads per second.
