Nothing to miss, they are old and sick GRANDMAs, and I guess You don wanna see them naked...... They pray for rain by doing so as this is the culture there, I guess, thats what these old sick ladies can do from their home so that their sons and grandsons have a good harvest. Do not expect a young in her sweet sixteen being naked in the middle of the field...... if it is, BBC and CNN and FOX news will be there before you as they have nothing more to do nowadays...
