I love a breathlessly long line! The Flea just accepted a long 3 part poem of mine
(The Banyan Tree And the Bathers) which is in heptameter and which ups the ante even further with eighteeners and [gasp

] even nineteeners thrown in for good measure.
"Then all the noise and movement of the street before me seemed a sort of dance,
this melody inaudible maintaining order in this realm of chance."
