I was considering a Hotdog stand and figured the best thing to get around on, store and be practical is one of those 3 wheelers (sort of motorbike with a flatback welded on) that get made by a guy in Sosua, if you were handy enough to stick your kitchen on the back. I have no idea of his name, but I used to see him and others he had sold around town all the time and thought them to be really practical for things like this. I haven't seen them at all since moving to Santo Domingo. I'm sure he won't be the only guy to make these things but it might be a start if you are in that area.
I'm sure someone living in Sosua will beable to shine a bit more light on what I'm talking about.
