getting a speed ticket

[Hero1]

I just got a speed ticket today :cry: , I'm very very pissed off about it, the police said I was speeding on a 55 mph road with wet surface, and I was doing 72. but the road was dry and this is how fast everyone drives on highways? :x I really think I'm a victim of the quota, I can't afford to have my insurance any higher, I am gonna fight the ticket, anyone have any experiences or advice, please tell me,thanks
