I am trying to locate a poem that I read years ago that deals with why
the writer did not like/enjoy poetry. Or perhaps it dealt with the
only kind of poetry that the writer liked. I am almost sure that the
writer was Carl Sandburg. I seem to recall that it was sort of a spoof
piece of poetry. The poem was fairly long too as I recall- like 30 or
40 lines as opposed to 5-10 lines. I know it seems strange, but I also
seem to recall that it made mention of a train or locomotive in it
somehow. I would like to at least know the title of that poem. A url
pointing to the poem itself would be great! A book title that contains
the poem would be acceptable in lieu of the url.

This isn't Sandburg, but it is a humorous poem that is critical of
poetic metaphors:
