"Gratitude to Old Teachers," by Robert Bly

A poem in blank verse--not typical of Bly. But it has his characteristic surrealism, offering a striking comparison, to say the least, all in the context of walking across a frozen lake, no doubt in Minnesota. Bly's book about surrealistic poetry, Leaping Poetry, is terrific.
