Raccoons living in urban areas do tend to be less wary of humans than their rural cousins. It is not unusual to spot one during the day. Particularly if there is a potential food source available in the area...such as a grill. In order to keep unwanted raccoon visitors from coming into your yard you'll want to: keep the grill area clean, do not leave any pet food outside, and secure your garbage cans. Raccoons are smart, strong, and quick to exploit easy food resources.
