“…we don't need roads.”
I've heard it said many times that you should always bring your camera with you. Some days I do and some days I don't. I was happy I had it with me today though (lesson learned?) because I walked outside today and parked next to the office building was a DeLorean.
I've never claimed to be a huge car buff. However, I am a huge Back to the Future fan. One of my favorite movie memories comes from a back-to-back run through of the entire trilogy with some friends. Classic.
Your sign says “Vacuum Hose Routing” but I'll take that as code for “Flux Capacitor Wiring.”
