Driving in the D.R. can be very dangerous so if you don't know how the system works then please do not drive.  Here are some examples:

The person with the right of way is almost always the one who got there first, or, the biggest vehicle.  

Everyone uses the horn because it's there.  

If you ever get caught by the Police for a traffic violation it can be easier for a foreigner just to pay him off with may 100 pesos depending on how severe the situation.  

There are speed limits but they are just recommendation.  Really most travel as fast as their car will let them without hitting anything in front of you. 

Passing cars can be done on the shoulder, sidewalk, or other lane depending on what is most convenient.  

There are many more motorcycles than trucks or cars and they can appear from nowhere, so just listen for the unmuffled engine as they roar around the streets usually carrying a large load like a six foot propane tank. 

The main thing is to just remember that driving in the DR is an adventure.

Food preparation varies greatly among the rich and poor, although the food eaten is   common among both.  Dominicans favorite food is the "Bandera" (flag) which              consists of rice, beans, and meat, and is eaten daily by most. Their main meal is during lunchtime right before siesta (1-3 pm).  Here are some other interesting things     I've seen when dealing with food:

ice is frozen in bags called "funditas" and broken-up with a spoon,

 car wheels are used as stoves,

if there's meat sitting around you need a fan or use of hands to waive off the flies,

 mondongo is a special treat for many which consists of boiled animal intestines,

 their lemon juice is used as a cure-all,

and after a month of eating Dominican food I became addicted for life because it is very satiating and mmmm tasty!
