I seem to recall the Third Amendment is specifically about one’s house, and doesn’t apply, to, for instance, one’s barn. Which actually strengthens the argument that the Second Amendment is not limited to one’s home, since the Founders could easily have included the words “within a citizen’s home”, but did not.
Here's the Third Amendment:
No Soldier shall, in time of peace be quartered in any house, without the consent of the Owner, nor in time of war, but in a manner to be prescribed by law.
The phrase "quartered in any house" may have implications beyond just where a soldier's bed is located. Who feeds the soldier? Who prepares the food? Whose pots or cookware is used. Who supplies the fuel for cooking? Who launders the soldier's clothing? Who tends to the soldier if he is sick?
The real meaning would have to be found by examining what abuses the Founders were trying to eliminate. It's not at all clear to me that such abuses would be avoided simply by having the soldier sleep in the barn. From what I have read there have been no court cases addressing the Third Amendment.
Using that logic, the First Amendment should apply only to the print media, since we didnt have radio, TV, cable or internet in the 1700s.
