The only positive I can see to that bill is you wouldn't be hassled for having it in the car if you stopped in a park on a trip/vacation.
Concealed carry in the park? No.
Visiting the Liberty Bell? No.
Smokey Mts? No
Grand Canyon? No.
Olympic? No.
Everglades? No
Mt McKinley? If you're hiking in Grizzly country...a big one and on your hip, not concealed.
Generally not needed...it'll die in committee.
