Dave (Doc Nock) you brought up an excellent point. Dragging it out was a real chore that I made a bit easier by walking back to the truck and returning with a piece of heavy plastic sheeting, they used to call this a "deer sleigh'er", that forms a slicker surface to drag on. But, then I got back to the truck.
By that time, the deer weighed in the neighborhood of 600 pounds (dressed !) and I looked at the pick up , then looked at the deer, looked at the pick up, and looked at the deer and then almost started to cry. Now what ?
I did something I never did before and it worked. Yeah, this buck was heavy, but part of the reason it takes two to get them into the bed of a truck is cause there are no good handles on a deer. Sure, some in front for dragging, but not for picking it up (unless you are REALLY tall).
I took a couple strap-on tree steps that were in the truck, and cinched them around the deer's torso, one just in front of the rear legs, one across the chest and between the front legs. With these straps in place as hand holds, I was able to dead lift the critter up and plop him onto the tailgate.
Hooray ! it worked.
