So he turned out to be 110lbs. No giant by any standards, but will certainly taste great. I have to admit I was wishing I had Nick's Game Trolley. It was dark when I found him and I headed the wrong direction to the truck for five minutes(forgot my compass). Thankfully I got a little cell service and used Google earth to check for the pin I dropped at the truck.
I now have a flashlight/compass app and a GPS app on my phone just in case I leave the pack behind again.
