The dog of the South

"Ray Midge's wife, Norma, has run away with her creep of a first husband. She also ran away with Midge's credit cards and his Ford Torino ... But Midge can track the lovebirds' escape once the credit card receipts start rolling in, and he sets off after them to get his car back. The route: from Arkansas through Texas through Mexico to a remote, bedraggled plantation in Honduras. Along the way, Midge meets Dr. Reo Symes, a down-on-his-luck old Texas M.D. with some hapless dreams and a broken-down bus called 'The dog of the South'. The further south the journey takes them, the wilder their days get."--Publisher description.
