As much as love this sport of ours, blood trails make me really nervous. Perhaps it relates to being on a bloodtrail of a dead deer walking, when I thought the shot was perfect, only to bump the one-lunged monster. I did find him a 1/4 mile and 8 hours later but it did something to me. Kinda like getting snakebit did. I hate snakes because of one little cottonmouth. Also, I had been unlucky enough to have looked for several "no finds" including a couple of mine. As much as unraveling the mystery is just plain fun,the fun goes away without the pot at the end of the rainbow.
I'd vote for going down in site every time. Bloodtrails can be beautiful things but to me nothing is more stunning than seeing a white belly from stand.
