You've stumbled across an Easter Egg...  An undocumented feature of the NavyThriller.Com website.  If you look around, there might be others.  This one is proof positive that I am a multi-talented man.  Not only am I a columnist and a novelist, I'm also a master horseman.

Here I sit upon my mighty steed.  Look upon my majesty and tremble...

Maybe the next Easter Egg you find will be something better.  Then again, maybe not.     ;)
