Someone propped an iron bed frame against a tree and over years it became entwined and engulfed by that tree and three later arrivals.  There are any number of aphorisms, proverbs, or life lessons that could be trotted out with this picture as a backdrop, illustrating the slow but inexorable enveloping of time and natural forces.  I can hear the cadence and final fall of Garrison Keillor’s voice as he reads this picture as a poem (no disrespect to Mr Keillor intended, but if you’ve ever listened to A Prairie Home Companion or The Writer’s Almanac you’ll know the kind of poetry he favors and how such a poem would flow).
