LONGLINE

To take a very long and grueling trip. The meaning is derived from the name for the long distance phone companies' lines (long lines, which are either copper or fiberoptic) that stretch quite lenghty distances, usually continuously from coast to coast, or within the continent outside of the US (to Canada or Mexico). Example: Jim's gonna be gone for the next couple of days, he's got to longline it to San Francisco to Boston by car.
