Carry in National Park but not Buildings?
On a recent trip to AZ, we visited some National Parks. Tried to search the forum, and research online, but no results.
When we got to the sites, the information buildings had signs posted "no firearms" with a citation to law. I assume this refers to federal buildings like post offices etc.
How can I be ok with my CCW at the park but not the ranger booth? In one park, you could not enter without paying the entry fee, but that was in a building with the no firearms law.
