Jacob looks around the park, but is unable to find any signs whatsoever that even a normal wolf had been in the park, let alone the giant one that had been reported. Though even if it had actually been there...that call came in a long time ago.
The penalty on a tracking roll is penalized by one for every 8 hours it's been since the quarry has passed through the area. Running with Wild Senses closed 12 days before this thread began, so that's the time period I will use to calculate the penalty. So five days equals 288 hours which can be broken into 36 8-hour periods. Meaning that any roll made to find traces of something that happened that night is at a -36 penalty, at which point I'm automatically considering it a failed roll. Note, that this also means that Doug is unable to pick up any sent trails from what happened.
