the canoe sites are filled with storys of people setting
them off in the far north of Canada because they were
tired and wanted to go home..these things could turn into
another version of the easy to use CB radio that boaters
used to call for help from the Coast Guard because they were to lazy or cheap to top of their gas tanks and knew the CG would
show up to gas them up...thats was some years ago..the CG maybe
charging for those kind of "rescue calls" now..
