When you consider that you do get charged for ambulance transport in most local NH towns, (but not in Alton), maybe you should be a smart consumer and consider your options. Is going to a hospital really necessary, and is there another way to get to the emergency room such as driving yourself or getting help from a neighbor or someone? Boaters all around Lake Winnipesaukee have always been extremely helpful to come to the aid of boating accidents such as a fire or a capsize, and it would probably be very easy to get someone to transport you without incurring the $5,000 ambulance transport expense.
Back in August, 2006, a 64-year old Vermont woman, being transported with minor injury to her head and foot by a local NH or VT town rescue boat was drowned dead during transport because she was strapped into a transport carry litter and secured to the bow of the boat, an airboat, and the bow got submerged, or something. Do not recall all the details?
