Let people know before you ride it.
I doubt that the authorities would make much of a fuss, however, don't get into trouble out there.
Make sure that you let someone know where you are planning on going, and how/when you are planning to get there. I really don't want to hear about the body of a cyclist who died from exposure after getting hurt/lost being found on a road that was closed.
Be careful out there!
Riding my bike is MY pursuit of Happiness!!!
