Rochester is the famed winter home for 30-thousand Canada geese. The wild birds stay mostly in the center of the city on Silver Lake, which does not freeze because of warm water from a nearby power plant. While the healthy flock is a source of some civic pride, their by-product is the bane of locals. One Rochester man, however, has found a use for the waste. Gary Blum (like plum) turns dried goose poop mixed with glue into art. He's found a niche creating pictures of geese, loons and even people. Minnesota Public Radio's spoke with Blum about his passion for goose poop art. Rochester artist Gary Blum talking with Minnesota Public Radio's Art Hughes.
