There are many lucrative businesses here in the DR. The thing is some posters here don't have a clue, or maybe they at one point had it and forget, as it may be in CC's case.
For example, Pancho Motores in Moca moves a lot of bikes because in the campo, bikes rule. They also have contracts and require work references or guarantors. Also, no doubt they have an agreement with the local police to confiscate bikes if payments are not made. In fact one of Ramon's friends is a detective(he is my friend too) and no doubt helps out. I expect the threat of spending a night in jail is enough deterrent for most. It is not w/o it's risks, Ramon has had at least one attempted robbery where he was chased in his car.
Also, my father in law runs a micro loan business in the campo and he carries no gun and is in fact a small and pleasant guy but does require a contract.
