I had avoided tickets for many years on US 81 between Vance AFB (Enid, OK) and Oklahoma City. I had heard from numerous individuals about speed traps in the small towns along this stretch of highway so I always paid particular attention to my speed. Unfortunately I recently got a ticket coming thru the small town of Dover late one evening (1100PM). I was making an effort to slow down but apparently not fast enough and was supposedly clocked at 50 mph in a 35 mph zone. Long story short, I now owe the town of Dover $169. I suspect the town uses the speed trap and the associated fines as their major source of income.
