Sounds very appealing. No noisy neighbours for a start, no traffic noise (lovely). But of course with everything this is a downside - a medical emergency for one, inclement weather when it is time to bring in supplies. But one can dream!!!!
I wouldn't like to be so isolated. I love being able to walk to the mail street to pick up a library book that is on hold, to have a cappuccino or buy a couple of items from the shop. I love being able to walk to the Sunday market to buy vegies. Having to use a boat to get to shops, train, doctor and all the other facilities one uses would drive me crazy.
