Speeding ticket rant

In Montana thier law was stated right at the border on a big sign...."Trucks 75 daytime and 65 at night. Cars are regulated to a safe spped given the conditions." IIRC. I was blasting through at what I figured was a safe speed given the contitions at 90 mph. I saw a cop way behind me and slowed to a tick under 90...... He passed me doing an easy 110-120, no problem. It was clear and dry and I was on my way to my uncle's funeral of which I was to be a pallberer. This was about 1998. On my way back I was passed ( I was doing 90 again) by some guy in a new mustang with IL plates doing maybe 120-130. Sure enough, 10 minutes later I saw him pulled over.......
