I went camping over last weekend and brought home a few nice specimens. I also purchased a focusing rail from Adorama. Best $20 I've spent in a long time. I can fine tune my focus and DoF so much easier and better now.
Be careful. Wheel bugs have been known to pierce skin in their defense.
I read that last nite. And from what I understand, it can take several weeks if not months to heal, due to the enzymes they inject when they bite. Fortunately, I found this one already dead. :)
