"Set out for the open road with the Simpsons as Homer becomes a trendsetter for all that's hip, cool, and chic in the world; Grampa relives his days as a starry-eyed surfing stuntman and soldier of fortune; Bart reunites Groundskeeper Willie with his estranged brother on the rolling hills of Scotland; Nelson Muntz becomes an unlikely part of the family; Krusty the Clown loses his way and his identity; and while chaperoning Lisa's class on a trip from sea to shining sea, Homer takes to the highway and weaves all over the map with his own hysterical history of America." -- pg. [4] of cover.
