Gene,
I didn't ask and he didn't say. He caught me so off guard when he said he send me some. He just said he ended up with some chips and he and friends played poker with them from time to time. I'd guess he would have been just a little kid when the chips were made. He did mention they were used in the early days of the bar and that it opened in 1981. I noted some of the ads and web sites about Billy Bob's mention a casino as part of the attractions but that's all I know. I don't want to bug him anymore.
