so close and yet so far away

We arrived at her 'home' last night at 5:30. She wasn't observed until after 9 pm which is very late for her. Usually the spanish speaking residents a few doors down see her around 7 pm at the latest. We trudged through thickets of briars and poison ivy and located what we think may be her den but she wasn't there. Moved the trap to nearly directly in her patch and made sure to fill it with great food. She didn't fall for it. She came back 3 times and each time she'd eat the food leading into the trap but wouldn't seal the deal. Finally, near 1 am, we left and will try again tonight. We need help flyering around the high school, nearby parks and churches. She appears to be expanding her travels. I also need help with literally sitting into the late hours and monitoring the trap. Catching raccoons and cats isn't helping the situation at this point.
