Man O Man O Man O Man.... that is AWESOME... and what a Great Story... made me feel like I'm right there with you.... nearly... which would have been better...LOL. That was great you could do it with your Dad... not everyone can do that.... you are Blessed indeed. This story deserves Blue Font....LOL
I'd cut off the back of that shot case and embedd it into that rifle stock somewhere as a notch of memory.
Once more... CONGRADULATIONS...and to your Dad as well...that is the BEST kind of TEAM WORK.
