Poo Free Parks started in the Denver Metro area by providing Earth Friendly cleanup stations and bags, along with weekly service, to park systems, HOA's, and other agencies at minimal cost to dog owners/taxpayers. Poo Free Parks then secures local and natonal sponsorship advertisers to help subsidize the cost for these supplies and services. Businesses place their advertisement on signage attached to each clean up station within the dog friendly parks. Poo Free Parks is now located throughout the Denver, Portland, Southern California, and Chicago metro areas.
