Shawn --<br><br> Where I live (St Croix US Virgin Islands) meets your definition of a tropical island, even if 50,000 people share it.<br><br> But on the water issue -- here, like in most of the Caribbean, standard building practice is to catch rainwater on the roof and pipe it down to a 20-40,000 gallon cistern under the house. That's all we have to rely on, since there's no "city water" on most islands. (No sewage either, so you have a septic tank.)<br><br> Comes a drought, the water trucks from the desal plant keep you going (or washing, at least.)<br><br> -- Karl
