How are y'all carrying deer meat from TX into LA?

Right at the border, we throw the heads into the Sabine going bout 85 mph

And keep it hidden. Don't have any horns showing or hunting gear if you can keep from it.

Meat isn't an issue, just spinal bones and soft tissue. If you kill a deer that you intend to mount you need to cape it out like a taxidermist would and cut the horns off leaving them attached to the skull plate. Peal the membrane off of the inside and clean it with water. You shouldn't have any problems doing this, other than it's a pain to cape it off the skull correctly. I recommend a set or razor blades and a screwdriver to assist.
