Random Thought

Gette came to visit and we went to see Desolation of Smaug again and I had a random thought. Dwarves are what, four feet tall? The inside of Erebor is big enough for a giant dragon to move around freely. If the dwarves of old had built gates and halls a little closer to their own size, it would've been a lot harder for Smaug to get in. I'm not saying it would've stopped him completely, but it would've taken him a lot longer. Maybe the dwarves would have time to evacuate the non-combatants and set up a feasible defense while Smaug had to claw the stone doors and hallways wide enough to squeeze into.
