During the day before I-10 crossed into Mississippi from Louisiana, driving into New Orleans, LA, was via U.S. Highway 90, and the stretch from Rigolettes Bayou to Chef Menteur was a curvy stretch of two-lane highway that connected Lake Pontchartrain and Lake Borgne to New Orleans and the route was bounded on both sides by marshes. Along this route, there were hundreds of camps built up on pilings with footpaths that went into the marsh. Just off the highway there were all kinds of fancy signs telling those traveling the road about these camps. Most of the signs were homemade and one resembled the picture on your chip. There was an abundance of hunting and fishing camps where hoards of folks spent weekends to get our of the city. As a teenager, I remember riding with my dad to work at Chef Menteur, and enjoyed seeing all the clever slogan signs along the route. The people who owned the camps did a great job of building log frames that were used to hang signs. What makes me believe I saw that sign is the black lab image on the chip's face. Being a duck hunter at an early age, I thought that location was a training school for lab retrievers. According to my dad, there was gambling at some of the more elaborate camps, but he did not admit he had been a customer at one. Could the Pont be an abbreviation for Pontchartrain, and Chippi short for chipping. Maybe, it was not a retriever dog training school after all. Hope this makes sense and may be a missing link in your quest to identify the chip.
