Standard apparel here is collared shirts or poloshirts, khakis or jeans, shoes and socks.
this applies to all cities and towns. Shorts are considered to be "girly man" attire.
Women in short shorts are considered hookers and will be so treated.
Lots of jewelry? "Please come and rob me, mister"
About money:
Spread it out. The ATMs here will let you have enough for a dayor two. Plastic is accepted just about everywhere. CAsh in a couple of pockets.
Be nice. If you are a visitor, be nice. You do not have to become "blood brothers" with the staff, but do be nice. Smile.
Learn a few phrases, like "C?mo Estamos? " (the old-fashioned way to say HI!" Dominicans love to teach you how to speak...
If you live here, know your neighbors. A sancocho on one of these evenings with beer, toasted casabe with garlic butter and chicken and a few pork chops....Rice, avocado....and this just for the closest neighbors...
Dominicans love to ask personal questions: How much do you make.? How much did you pay for the house? stuff like that. Be very vague.
In the cities of the "interior" , like where I live, the thieves are seldom "random". Often times they have ties to your help or are actually part of your help...
Lights are good for nighttime protection. So are yappy little dogs. Big dogs tend to discourage people, and this is a good thing. Butthe yappy ones tell you someone strange is here...
A firearm is for killing people. Showing it off doesn't do much unless you are willing to pull that trigger, and know how to do it! Train yourself if you can afford one.
Someone once said that fences make for good neighbors. My mother sometimes talked about "spite fences" ....at any rate, good fences can be a major deterrant, especially now that razor wire is available... There are bushes that are beautiful and impenetrable, so a lot depends on your space.
Enough ramblings..
