Greg it stands to reason that Tarpon are there,i mean if they're in Florida,Cuba,Puerto Rico&Trinidad there MUST be some in the DR.
i've looked high&low on the web for info on fishing the DR,scant is too kind a word for info on fishing the DR.
i suppose the thing to do is get to a place near some mangroves and start asking the boys on the beach about Sabalo,then just go for it.
