Dear Editor, I am writing to suggest that the Parks and Recreation Department or the city of Austin does not close the off-leash area of Bull Creek. I have been taking my dogs there to swim for years and years (unless, as lately, drought conditions prohibit safe swimming). It has been my experience that about 90-95% of the people who take their dogs there bring their own or use the city-supplied green pet-waste bags to clean up after their pets. Has anybody ever thought that the high E. coli numbers are from the dozens (if not hundreds) of human "poopy" disposable diapers left behind? I can't tell you how many times I have seen used, full diapers on the ground, on picnic tables, picnic benches, near the restrooms, etc. This disgusts me! Often there will be used diapers right next to the garbage containers! I am not a scientist, but I hope somebody has tested the water for E. coli in human feces. It can be found in human waste, not just dog waste! Please take this into consideration before the city of Austin decides to permanently close the off-leash area of Bull Creek. I'm begging you; my dogs are begging you, too. Down with dirty disposable diapers left behind by humans!
