Neutral Ground in New York City has a weekly Legacy tournament on Tuesdays @ 4PM
There is no fee for entry but unfortunatley no prize as well, but it's good practice.
It's not worth coming from far away but if you live in NYC and you are interested in Legacy (I think there's probably 3 of us so far) come check it out. Just figured I would get the word out.
