Ya Gotta be 21 to Buy a Beer, How about 21 to Buy a Gun?

[AMart]

I'm pretty sure the legal drinking age in all states is 21, meaning you can't be served in a bar if you're not 21. Several states allow drinking under the age of 21 if the person is with a parent or guardian...

Yes many states allow drinking with parents/guardians some even allow for that in restaurants, the home, outdoor camping stuff like that.
