I noticed in todays new Chip Guide items there is a 181 chip listed as an unknown. It is a known chip. It's from The Avenue in Bellevue, Ky. I visited Duke Mile about a month before he died.Duke was the owner of The Avenue. He told me the circumstances about the fire that destroyed the club and gave me a 181 chip from a full box he had. There can be a no more positive ID than that.
