I carry a tape... because I like to take measurements of the hide before I skin it so I know what size the hide is, what the placement of the horns/antlers are on the mount, the angle of them etc...
I think I"ve rough scored about 3-4 of my deer in my whole life just out of curiosity, but always when I'm in the mounting process of them....
Of course I dont' care who else carries a tape, but its damn sure not to come up with a score on the hunt... that never matters.
I've said it beofre and will say it again, to this day so far, I have 2 trophies that mean the most to me. One is a whitetail doe. The other was an 802 yard shot on a small caribou bull. Both grace my wall due to difficulty of the hunt, and both bring back more memories than my largest whitetails so far.
