Ya, there are lots of small communities that are not accessable by road. You either fly, boat, or wheel.
I was flying over the area inland of where the above crawling pics were took a while back and out in the middle of BFE there was an active homestead. What caught my eye was what looked to be a super nice (from several hundred feet in the air) early chevy short bed. Im assuming that he gets supplies via 4wheelers in the summer and snowmachines in the winter.
