This may sound odd, but I don't know of any 4 way stop signs in Crook either!
There may be one off the beaten path, but the main roads thru Sundance, Moorcroft, and Hulett have no stops at all!
When I lived in Pahrump, NV, they were planning on putting in a 3rd traffic light. It was going to cost ONE MILLION for the light at the intersection of a well used boulevard and the main highway. ONE MILLION! Of course, it wasn't just for the light. They had to "improve" the intersection with proper drainage, shoulders, widened right of ways, cross walks, and lighting! They finally put up a "temporary" light costing hundreds of thousands and are still waiting, for 4 years now, for the permanent traffic lights.
Geez, I'm glad I live in Crook County!
