Any time you expect things to go well is when they mess up. It is the nature of the beast. Glad to hear you are back in the saddle with the rifle, and I hope your back heals up.
I somehow threw my back out yesterday from of all things, splitting a little firewood with an axe. I mean come on, I split wood with an axe since I was old enough to swing one.. Nothing an advil can not handle mind you, but I guess old age is a terrible thing...
