Thanks everyone for the encouragement. Being called "crazy" motivates me to no end.

This is probably the most ambitious project I have ever taken on.
I do have plans for both a rear gun and a deck canopy. The gun will probably be some kind of promiscuously firing weapon mounted on its own little balcony.
The decorative railing is a Grandt line product I found at the local railroad model store. Its called a Wells Fargo Railing I think.
Tonight I hope to tackle the detail work on the balconies and maybe get started on the deck.
