Via the New York Celtic Supporters Club FAQs:
Is there any place to avoid in New York City ?
New York is one of the safest places around these days and anyone exhibiting common sense should not run into any problems. The lack of a Glasgow Rangers presence makes for a pretty pleasant environment. However visitng Celtic Fans should note that the New York Rangers Hockey franchise despite being uniformed in sickly shades of red white and blue do not represent North American relatives of our cloven hooved friends.
Or as one Urban 75er puts it:
"as my friend dara once said to me "our bigotry's so much more romantic than yours".
