show up in court on your assigned date. wait until the DAs tell you all what's up. the DAs often will bargain the ticket down a notch or 2 in return for you not fighting it and costing the county even more $$ to empty your bank account. this has worked for me and saved me many points on the license. I have gotten away with the old "hope the cop don't show up" thing a few times, but don't count on it. Nowadays in Maine they don't actually have to physically be in court, just available by phone or by brain waves or whatever...and it's the DAs who do the "contacting" so you are probably gonna get whacked anyway.
don't actually try to fight it unless you have conclusive proof you were not speeding. nothing pisses off a judge more than some line of hooey...it usually comes down to a yes-or-no question: "Were you speeding or not, yes or no?" you might not believe the cop, but if he's got you on radar, you are hosed. period. if you piss off the judge, you are gonna get the first degree and pay top dollar in return for a hard learning experience about the justice system.
good luck, with 65 in a 30 you gonna need it.
