Im sill trying to figure out how she made the money to deposit on the trip......
Just thinking...at first my mind went into the gutter, but then...
What if she had paychecks, but when she left at 5AMish from Yreka, the banks weren't open yet. She needed them put into her bank account so she could use her debit card.
So when she got to Monterey it was now banking hours (10AMish), so she stopped to deposit them in her bank's branch there.
There may be nothing more to those receipts than tracking her steps on the trip.
