Every state in the United States technically extradites, as the Constitution requires states to deliver fugitives from justice upon demand. States may choose not to extradite on a case-by-case basis, however.
A state's decision to attempt to extradite a fugitive depends on a number of factors, including the distance, expense, seriousness of the charge, the prosecutor's confidence in their case and the legal complexity in arranging extradition from the asylum state.
The FBI maintains a national fugitive tracking database called the National Crime Information Center, which police officers in each state check when they perform a stop or book someone into a jail. States must travel to pick up their wanted fugitives, however, and the states are allowed to name a maximum distance they are willing to travel to pick up the fugitive. If the distance is too great the state of origin is unlikely to even be contacted regarding extradition. The exact distances are generally not made available to the public and are not known to fugitives. Certain agencies, such as the law enforcement agencies of Philadelphia, choose not to extradite anyone who is outside of the state, even if they are only a very short distance away across state lines.
