Wow! And again Wow!
I've never really thought seriously about using something like a string tracker as I have a bit of a gadjet phobia when it comes to bows but following along with you in your story really drove the point home of the place something lake a string tracker really does have in archery. The first "big game" animal I ever shot with a bow was a turkey and while I made a perfect shot on a broadside bird at about 15 yards, it managed to get airborn and I never found it. It's bothered me for a lot of years that I lost that bird.
I'm not certain that I'd run out and buy a string tracker just yet, but I certainly look at them in a new light now.
Thanks for the story, the food for thought and congratulations on a fine bird.
