Moore Humane Society no longer has free adoption weekends. They realized most of the animals taken during free weekends were brought back to be rehomed.
Also, some of the smaller shelters do this. Google Midwest City, Edmond, Moore shelters. OKC animal welfare (shelter) is separate from OKC Humane society. They do partner to help animals but they are separate agencies.
There was an adoption event last weekend. My suggestion is to check okhumane.org for upcoming events.
