Changes

If you are trying to get to [[Pennsylvania ]] or points West, your best bet is to take NJ Transit to [[Mt. Olive]], [[New Jersey]]. This will get you out of the suburbs, and thus increase the likelihood of getting a long-distance ride. From the Mt. Olive train station, you can walk to the on-ramp of I-80. Be advised that hitchhiking is illegal just about everywhere in New Jersey, including shoulders and on-ramps, so use caution.
