Beware Una-Antioch and ALL of its side-streets. They will get you for not stopping "completely" at stop signs too. They tend to wait unitl there is little traffic (late morning, early afternoon, late evening) and LOVE to sit at the bottom of hills. However they’re strangely absent around the several surrounding school zones when children are present, for example Apollo (hmm. . . ). You’ll see them all week long during quota time. They tend to leave you alone if you’re 4 or less mph over the limit. I’ve had two tickets in ten years and my sister had one before we moved out of Antioch. Best to just avoid Una-Antioch and take Murfreesboro Rd to Bell Rd or to the interstate. At least you know where they hides there!
