An Entrance Fit For A King
Naturally, when you’re making an underground bunker, you need to have a way to get inside it. Wayne did the logical thing and laid down a set of concrete steps and made sure the top stair was at the same level as the top of his bunker.
I think most people would prefer a simple staircase to something like a ladder or a fire pole to slide down. Now that he had his bunker in the ground and the stairway complete, Wayne could set out on completing the exterior and get ready to outfit the inside.
