What exactly are the "In Transit" scans? With UPS there's only arrival/departure sscans when a package gets to an actual facility. If it spends 5 days on a train there are no scans. Fedex seems to scan about every 24 hours; is it tracking the 18 wheeler or something? I've seen some in really rural places, one was the town of Index, Washington where there is no place for a truck to park. Or does Fedex send by rail too?
