JD came over today and helped me de-palletize the new safe. It's a Cannon Oxbow from Bud's Gun Shop - I paid $799 shipped to my garage.
Here it is sitting in place and level - as of yet unbolted (and still empty).
And opened... it's a 24 gun model (either 22 or 23 cubic feet, I forget offhand).
Here's our puppy, Althea, inspecting the interior...
... and here she is ready to get out!
I've got to say thanks to JD for coming by after work to help me shuffle it around the garage, but it's only fair - I helped him schlep his up three flights of stairs!
