I'm from Chile; the Republic. I have a relative , a good cousin, who has a set of chronic diseases, producing a rather severe form of immobility..His life-long (or honestly "bucket list") wish is to be able to go all the way from bottom to top, of the Aconcagua mountain (located in neighbor Republic, Argentina), and\or do the mule track tour across the Andes.
IS this possible? Do some sort of "human carrying porter" services exist? Or more realistically, any equipment he can buy and learn to use, to -even with assistance- do climbing himself? Some sort of rope-pulley-wheelchair thing? He already does bouldering with great effort and help, but also great joy.
