Unfortunately, the tracking system for the United States Postal Service is not very good. If you live outside the United States the tracking will not work once it leaves the United States. It will show the last location it reported which will typically be somewhere on the coast. If you do live in the USA and your package is reporting strange locations it is most likely a problem with the USPS tracking service and your package will arrive without issues. Hopefully their system gets some bug fixes soon but for now, it seems to be rather hit or miss.
