We are planning a trip on our bicycles from Key West, Florida to Bangor, Maine using the Adventure Cycling Association maps. We want to download the watpoints from their website and plan our trip on my computer. After the trip we will be living and crusing on a sailboat and also want to use the same GPS for direction while on land in port to locate service facilities.
