Poke,
While I've seen a few installation works similiar to this one (Shoes on highway guard rails commemorating drunk driving deaths, etc) the profound sadness of these works never lose their weight. When I see worn shoes I am always reminded of two disparate images of our lifetime....the rooms of shoes from holocaust victims piled in obscene mountains (the worst of times)and the photograph comparing a fossilized footprint of a distant ancestor (in Tanzania) and Armstrong's imprint in the dust on the moon (and the best of times). To me, no other article of human attire conveys the gravity of a life 'lived' as a pair of worn shoes. Thank you for posting your photos and thoughts.
