I usually use one of those 5 day igloo coolers. Put a thick layer of towels in the bottom. Add your meat dish in a sealed sanitary container and cover with another layer of thick towels.
Works great and have used the technique many times.
"I must say as to what I have seen of Texas it is the garden spot of the world. The best land and the best prospects for health I ever saw, and I do believe it is a fortune to any man to come here."
Davy Crockett, 1836
