For Throwback Thursday this week, we go back to April 2005 to US 15 in Painted Post, New York (this section of road is now part of I-99 as well). At the time, there was a sign for the Gang Mills exit where a NY 417 shield with a white background was affixed to the sign. I believe that it had to do with a maintenance swap that took place a few years prior. The sign is now long gone, replaced with something not quite unique.
Recently I made a visit to Universal Studios near Los Angeles. While on the back lot tour I came across a piece of infamous movie-borne fictional highway infamy; the location of town square of Hill Valley, California on US Route 8/US Route 395. The above photo is part of the intro scene to the first Back-to-the-Future movie which was set in 1985. To anyone who follows roadways the signage error of US 8 meeting US 395 in California is an immediately notable error. For one; US 8 doesn't even exist anywhere near California with present alignment being signed as an east/west highway between Norway, Michigan and Forest Lake, Minnesota. To make matters worse US 8 is signed as a southbound route and US 395 (a north/south highway) is signed as an eastbound route. At minimum the cut-out US 8 and US 395 shields somewhat resemble what Caltrans used in the 1980s. Assuming Hill Valley is located on what would have been US 395 by 1985 what locales would be a viable real world analog?
