I have been looking for one of these for a very long time. I think this may be one of the few times I have found a chip in the wild that I was looking for to fill a whole in my collection. I don't think it is a rare chip but it sure was hard to find. Crystal Mountain was an Indian casino on the property where the Red Hawk is located today. It was one of those large tent buildings and there were lawsuits and access problems. It wasn't open for very long. When they built the Red Hawk they put in new off ramps from freeway US 50 and solved the access problems.
