Travel with retiree authors, Jim and Helen Whitworth, as they go on the road with their "new" second hand motorhome, Rex, who often seems to have a mind of his own. Jim wants to extend awareness about Lewy body dementia (LBD). Helen supports his efforts but insists it is his mission, not hers. She dreams of traveling in an RV and teaching. Jim isn't interested in RVing; he's been there, done that. When Helen, a retired nurse and educator, offers to teach about LBD, Jim agrees to spend the summer on wheels. During their first summer as RVers and hopeful teachers, thrift queen Helen and fastidious, patient Jim find their adventures leavened with crises as they trek from Arizona to Washington, with a side trip to Alaska. Seniors, RVers, and couples everywhere will relate.
