I think Jodi said she slept at her sister's house in Redding after renting the car so that would explain big a chunk of the unaccounted for 8 1/2 hours.
But as for when she actually got to Lodi and how much time she spent there before and after McDonald's is anyone's guess.
There are so many little things I'd really like to know (and ask her by mail), but jeeze... I don't even want her to know what my home address is!
If you ask her a simple question about where she was born you'll get a 20 page letter with her maundering on about everything from Geography to Astronomy to World Ethics. Of course she will sign off with the words 'Most humbly'. That's Arias for you.
