Walking doesn’t work. If the cops see you walking they will likely stop you.
Then they have you for public intoxication and whatever else they feel like throwing in. Resisting, disturbing the peace, etc.
Even if you are drunk in your own home and the wife or someone calls even if for no reason other than you are drinking, you can be arrested at least for an overnight.
It is weird. Drinking is OK but getting drunk in any circumstances is all but illegal.
The voice of experience speaks.
So what make of lawn mower do you drive?
