If you have an Inpedimiento de Salida against you - easy!
Just go to Dajabon on a Monday and Friday between 9am and 4pm (ish) and walk across the border.
Is it your (friend's) baby?
Did they use a condom? Did it split?
For sure, your friend knows if there is at least the possibility that it could be his.
If it could be his, he has to have a heart of stone not to want to find out.
I have done the crossing around 50 times and I was never asked for my passport at the border - apart from the time I was smuggling my girlfriend over the border - but that was a different story.
It turns out that if you can carry something on your head or in a wheel barrow, you can take it through without scrutiny. My girlfriend would not travel in a wheel barrow so we/she got busted.
20bucks - problem solved.
Also, for best results;
Make sure you wear a Hawaiian shirt and have a camera slung around your neck. Wearing shorts and leather shoes with dress socks, and having very pale legs is also a good idea. Better still, go dressed as a god botherer. nobody messes with the lord's work in that part of the country.
