How Much Does a Bottle of Whiskey Weigh?

Thanks to Rick's frequent flyer perks, we each can check up to 75 pounds of luggage with no charge.  My bag weighs 35 pounds, Rick's weighs 45.  That leaves us 70 free pounds for whiskey . . . and other trinkets, of course.  A bottle of whiskey weighs around 3 pounds (yes I weighed a bottle) so that means we could, theoretically, bring home 23 bottles of whiskey, in our luggage, at no additional charge.  I doubt that they'd all (or our clothes) survive the trip but it's good to know we have the space.  Getting ready to go . . .
