I'm in Afghanistan too! But i'm not DOD. I'm Department of Army as a UAV Operator.
OP - best of luck with your ticket. I know I've been burned doing the same thing, but not at 100.
Where US 30 goes from Ohio to Indiana the speed limit drops 5 MPH. (65 to 60) So everyone coming INTO Indiana who doesn't know (or isn't paying attention, or in a hurry to get home) will maintain going a comfortable 7 MPH over, so you end up getting a ticket for 72 in a 60. Happened to me twice in a week.
I plan on using the 'speed warning' thing on my ZL1 when it shows up. There's a stretch of highway around Fort Wayne that is a divided highway from the start to finish with no where for a trooper to sit. I'll get in trouble on that highway in my ZL1. I topped out my caprice 9C1 on that strip at 146 hah. eek.
Best advice for court? Be respectful, courteous, answer questions when they talk to you, shut up when they're talking. Oh, and be honest.
