"Siggy and Hannes were disenchanted students and fellow conspirators.
With their horny haunches astride a 700cc Royal Enfield motorcycle they
roamed the Austrian countryside, living off the land and the landowners...
joined on their journey by Gallen, a long-limbed lovely hitchhiker... zeroing
in on the Vienna Zoo and Siggy's life-long objective: setting free the
bears."

This is the first John Irving novel and, regretfully I must add, it's my least favorite. The truth of the matter is, I never finished it. (sigh) Maybe one day I'll give it another shot and find within it a hint of the genius that was to follow.
