Reminds me of coming down off the Colorado Rockies. There are a couple of tunnels on the route.
As I was flying down into one in my Uni with all shoe manual brakes
I see a big sign flash on and say my speed is 72 MPH and it is a 40 MPH zone.

A couple weeks later I get a pic of me in my truck in the mail with the
plate number visible
and a ticket for a $100.00 or the option to come back and see the Judge. Yes I
mailed a check. I figure I got off easy.
