Son of a gun......a 90%+ success rate! My gosh, such statistics! Your town must be burgeoning then with "standing lines only" to get in those yolas. Hard to imagine how they keep that secret so well........ooopsss...hope they don't get mad at you for letting their "cash cow" secret out! With all that success it must be like a daily floating armada through the Mona Channel with all that success to be obtained!
Not every day, but I do know for fact that at least twice a month. Of course this is only a surprise to those who live in their bubble and all they know is what they read on the papers and hear from other expats...which would be OK if you weren't trying to state such things as fact (like you really know what's going on).
...and don't worry about people getting mad about this secret. What secret? Again it's not a secret to Dominicans. Plus they are too busy trying to make it to Puerto Rico to be reading this forum...
