Jon Bartlett,Yes, the East Coast has some pretty good turn-outs. I can't tell you the actual attendance numbers for the Mystic Festival, but they're pretty high.
We even had a nice turnout here in NYC for the Little Red Lighthouse festival in Manhattan last year.
In addition to that, we have a monthly Shanty Sing at the Seaman's Church Institute, near the South Street Seaport.
