Looks like mine's on the truck since mine just departed from Hodgekins, IN (9:06 pm central)and I don't see any plan leaving that area. So definitely mine's in the truck but that is fine is fine as it would only a 4 hour drive from where I live.My phones on the way from Louisville to Memphis stopped off in Nashville along the way.
Took about 2.5 hours to get from Louisville to Nashville. That’s also how long driving directions take it.
I’m betting Apple is getting these things close and then UPS is using trucks to get them where they need to go. Probably cheaper that way.
If you see not much activity over several hours and no flights leaving where there should be, this is probably why.
