Great article on securing a firearm in a vehicle

[DaveInOroValley]

I think as long as it was hidden well that it would be useful for those times when you're out and have to enter a restricted building. Although my understanding is that is in our state (Arizona) there are certain buildings ( A library for example) that if they have a no weapons sign have to provide a secure locker in the building for you.

I personally haven't done that but have read of others that have.
