I thought I read that it was damaging the coral? Is that true? If thats true, they should be banned...~~ As far as the danger part...they do say the same about our 4-wheelers here..and our snowmobiles..it depends on how they are used. Now I'm straddling..Another thing..if it isnt bad for the coral..who am I to say that people who live on this island should abide by what I want to see on vacation....This is their lively hood, not mine.
