We spent some time in Trini season before last. The crime rates are high. It is not cruisers related but anyone. Even the marina yards have problems. It was like walking around DC.
But if you think big city and prepare accordingly it is no more dangerous than most cities.
The is a second type of crime that doesn't involve muggings.
Work in Trini is not always that great. It can be relativly expensive and not all of the workers are of good quality. We saw many and know of many that were ripped off this way. If you are getting
work done there get refferences from some of the other long time cruisers.
