McMillan's full-page black-and-white photos give a documentary look to what is really a couldn't-happen fabrication about Jason's tricycle. Discarded by Jason's parents and taken to the dump, the tricycle falls from the bulldozer's bucket and goes rolling off--past a cow, across the trolley tracks, off a pier into a lobster boat, past the shops in town, and finally (after more adventures) right up to the stoop where Jason sits missing his trike. Set in Kennebunkport, Maine, whose residents posed for the photos, this makes simpletons of all the grownups involved--from ""dump man"" Ernest who chases the tricycle yelling ""Stop! Stop! You're my trash!"" through fireman Bob who squirts the tricycle with his hose to various head-scratching (""Well I'll be!"") and shrieking, package-spilling others. Their overplaying, along with all the local landmarks, gives this the air of a well-staged amateur production--great fun for those who know the cast and setting, perhaps a diverting curiosity for others.
