I found this old article and I found it interesting. Back in 2005 thenewspaper.com did a story on Missouris Biggest Speed Traps. Guess who's on the list?

#1 on the list (Country Club Hills) Guess what they have the speed camera now! Money ?
Missouri Filled With Speed Trap

St. Ann did not make it on the list at that time. With their speed camera maybe they will now, oh wait, they really don't have to report their money to the DOR because they do not have to have the DOR review the Ticket Violation.
