Reply #106: But it IS illegal in WA to be in possession of a firearm in public while "under the influence"

[Euromutt]

...and it's illegal to bring a firearm into a drinking establishment (i.e. any premises declared off-limits to persons under 21 by the state Liquor Control Board, for the benefit of non-Washingtonians).

I actually rather like the Washington approach; you can visit a decent restaurant while carrying, and you can even have a glass or two of wine with your meal. But you can't carry in establishments that exist primarily to serve alcohol for consumption on the premises, and if you've consumed to the point that you'd be a menace to public safety behind the wheel, you can't be carrying either. I think that's a perfectly reasonable state of affairs.
