I think she filled up the car and two gas cans. I have no idea why it wasn't done under one transaction though. Just like i don't understand her making two seperate deposits into the same bank account minutes apart. Unless this is her simplistic way of book keeping...
Are there double purchases of everything from Monterey on, where JA borrowed the gas cans?
If so, maybe her mystery caravan partner joy ride illusion began in Monterey?
And that illusionary caravan partner gave JA cash for the trip that she then deposited in her account/s, accounting for the multiple deposits.?. [Wink, wink!]
