That whole area from Maine up , is dotted with hundreds of islands . I sometimes thought one of those islands would be a good place to hide out , but come up with the same problems , food and winter . That far north is not the best for raising crops as opposed to other areas of the country . Not only that , most of those islands are hard rock , so digging a well may not be possible . Then there is the sanity issue …….Alexander Selkirk was marooned on an island for four years , and went a little bonkers with the isolation , he did come back to reality after rescue , but it took him awhile .
