Fence: Part 10 - Post Caps and Rail Caps

I finished installing the post caps and the rail caps on the front half of the fence. I drilled a single hole in the top of the post cap and counter sunk the screw. I may go back and fill the screw holes with some stainable caulk. My spouse and I really like the proportions of the post cap (it's 4.25" square), and they were only one dollar a piece (at Dunn Lumber). The only piece I have left to install is the fascia piece that sits below the rail cap (on the outside of the fence).
