Well first off
There is no such thing as a "cigar plantation" however we do have a bunch of cigar factories.
Most, but not all of the factories are in Santiago or nearby. In La Romana you have Tabacalera GArcia (Altadis) which is a major plaayer in the market.
What do you wqnt to see? Send me a PM or an email and we'll see if you want to come to Santiago for a while.
