Turning off of Yellow Springs Rd onto Mill Rd you head down & do not see or maybe notice Le Boulltier Rd on your right. That is where they sit & wait for people to go by. Speed limit is 25 but it is a road that you easily can go above that without noticing. Somewhere before that road the cops clock you so by the time you get there they step out & pull you over onto the side road for ticketing. I usually turn on that side road anyway & am aware of this trap but this day I got caught due to other things on my mind (like a death in my family). So be careful on this road, they pulled over 4 cars while I was there in just 5 minutes. They pull them, ticket them & off to the next.
