Suffering succotash! That's exactly what happened to me! $300 fine, "suspended jail time", 90 days restricted. Plus $700 to the lawyer. Fortunately, I didn't get any points on my record; it must have been reduced. I don't speed anymore, though.
"Substitute judge"? Maybe you got lucky.
I'm considering getting an inexpensive (non-ABA) law degree in the future so I can keep this kind of doodie from happening to me and my family.
