Abstract
One should keep in mind that the highest energy cosmic rays may be pho tons or neutrinos. We discuss the particle assignment of the 3 x 10(20 ) eV shower recently observed by the Fly's Eye detector. We show that the event is not initiated by a photon and that the assignments of pro ton and neutrino as the primary particle are, arguably, equally valid. Neither assignment is totally satisfactory.
