You’re indoors in the sense that you’re protected from the weather and the elements, and the cave could even have some kind of covering or entrance area that could be considered a door or doorway. People have built homes in caves.
Is caving an outside, inside activity?
Do I have to walk through the door? Can there just be a door at one of the entrances?
What if I enter a cave through a door installed in a doorway, but there are other entrances that don’t have doors?
What if you enter the cave through an opening where the door isn’t but I know the cave system has a door at one of the entrances elsewhere?
