KTJ,
Congrats on a great deer, but you were supposed to shoot it at dusk so we could see the flashlight blood-trail comparison! You could have gone back that night and made it a tougher test, lol! Actually, a couple weeks ago I had to go back to a blood trail the next day and retrieve a rechargeable spotlight that I got tired of caring when the battery died. I was a bit surprised to see how good the trail still looked. It had dried a bit, but not really darkened any. I hadn't seen a day-old trail in a long time, as where/when I hunt you either find them same night or lose them to spoilage or coyotes!
