Poop was not on purpose
The letter to the Editor in the September 10 about issue about composting blue dog poop bags really gave me a chuckle. The writer asserted that San Francisco dog owners collect dog poop in blue bags and then leave them around so they will bio-degrade.
Nothing could be farther than the truth. I have 2 dogs, live in San Francisco most of the year, and can assure your readers that not only do those blue bags not bio-degrade, but that there is no general debate at all going on among San Francisco dog owners about the righteousness of leaving dog poop around on the streets in blue bags.
They do not compost and it is illegal to dispose of dog waste in our green composting bins.
My guess is that the blue bag was dropped inadvertently and that the owner probably had no intention of leaving it for your reader to discover.
