Sorry AKIMbO, I have a lot of stuff to do, so tonight, Dying's not on the menu. I've somehow lasted the last -4 days, so I'll be fine.
I expect the return addresses mean either the sender works for the USPS and is forging them, or there are multiple persons involved (or they do a lot of travel)
Montery Park address means sherryton could be one.
I don't think it's him, but didn't I read once that Haata travels between Canada and California sometimes?
