Hope I can help to bring this post to an end. If some would do a little reseach there the info is out there inatead of going on and on. "CREDIT CARD BILL OF RIGHTS of 2009" has an amendment linked to the measure that permits CONCEALED wepons in national parks "WHERE ALLOWED BY STATES".

If the state says you must be a resident or that you need their gun permit an outsider would meet with restrictions. Few states honer other states hand gun permits. BILL
