The Dominican Republic will host the Pan American Games Aug. 1-17 in the city of Santo Domingo, and Americans attending should take the usual precautions against petty crime. In addition, use only hotel taxis or those ordered by phone from registered companies. Credit card fraud is high, especially at ATMs, so remain alert to persons around you and if you have difficulty inserting your card or obtaining cash, try a different machine. The island is susceptible to hurricanes and the games will be held in the middle of hurricane season, so keep an eye on weather forecasts.
