I've looked under many rocks. I seem to be kindred souls with Europeans, but you have to search for an american willing to do more than lounge, drink, and eat, or worse, take advantage of desperate conditions. I hope there are some exceptions here.
I have found a few Americans that were ready to do the rental car vacation in the DR. You know, fly to say Arizonia rent a car and hit the grand canyon, painted desert, petrified forest, meteor crater, etc. They knew cerveza, por favor, and gracias. They heard good things about the DR, so they came to me for advice.
I'd tell them about my first DR experience. Military checkpoints, searches, shake down by military police, picking up a school girl "hitchhiker" that wanted a trip to the cabana (yeah, i was that naive). And, of course, the wonderful Dominican people that are 99% wonderful. I pushed them towards a AI or a tamer country.
