Just South of State Line Rd. there is a neighborhood entrance where the police park their cars out of sight, get out, & clock the North-bound traffic on Horn Lake Rd. with handheld radar guns. There is a 10 mph limit drop (45 to 35) about 150 yards South of this location (@ the Southaven City Limit) with no warning sign. Alternatively, they sometimes set up in a church parking lot @ Horn Lake Rd. & Desoto Rd. where they watch the SB traffic that may be speeding up for the 45 mph zone entering the city of Horn Lake.
