They used to sell it on base at the commissary (horse meat). I heard about kangaroo meat too but I don't think they have it anymore.The Africa thread talk of eating zebra reminded me that I have in fact, eaten horse meat.
My grandparents were very poor. They received various canned goods from the .gov (state version) back in the early 70's. One of the meals I had when we visited was canned horse meat. VERY stringy, odd taste but with some strong gravy it was OK.
