I was there for the 2010 one - and highly recommend.
Had about 6-7 vendors selling their jerk chicken and pork with rice/peas and a few other side dishes in addition to 3 Dives.
Also a few crafts vendors and a couple vendors selling toys and glow necklaces, etc for kids.
A lot of locals brought their children early. They had a children's dancehall contest for them - very cute.
Then just a little after sunset they had a jamaican comedy magician on stage doing several tricks.
It was great watching the reactions of even the adults, who I don't think had seen anything like it before.
When 2 volunteers pulled on the ends of a rope and supposedly removed the underwear of a third volunteer - it about brought the house down.
