Very nice! But my definition of a man cave/fly tying space is somewhere where I only need to clean up all my crap on my own schedule. What's also missing is a tasteful bar area with some decent scotch and good glasses.
I have no envy, that space is a little too precious for my take, not to mention there is no chair, microfridge, TV or pull down bed for pure escape. I'd for sure have a pic of a river where the goofy Fishing supplies pic is
