1. I would hunt the park edges first - which has worked in the past. Then, if the next week or two does not produce additional sightings, I would'shuffle the deck' by invading the park to get a look at what's holed up in there. By this time, you will be moving towards post rut so there will less to lose.

2. Of course, I would live in the unpressured park. But, I would come out to chase tail or eat - which is probably why the yellow/blue dots are successful spots.
