  Protons accelerated in the internal shocks of a long duration gamma ray burst
can escape the fireball as cosmic rays by converting to neutrons. Hadronic
interactions of these neutrons inside a stellar wind bubble created by the
progenitor star will produce TeV gamma rays via neutral meson decay and
synchrotron radiation by charged pion-decay electrons in the wind magnetic
field. Such gamma rays should be observable from nearby gamma ray bursts by
currently running and upcoming ground-based detectors.
