Th Big Texan Diamond Back?
The Big Texan Restaurant in Amarillo is a big tourist stop...Free 72oz steak dinner if you eat it in an hour....about 2,500 have managed it in the last 40 or 50 years...I think.
Anyway, they kept a rattle snake in the gift shop and he just died. They also have a wandering music quartet that plays requests...when I asked them to play Waltz Across Texas for my sister, one of the musicians mentioned it was just as fun as "All My Exes Live in Texas"
