Heading either way on 37B (Lakeland Highlands Road), there are one or two spotters at the underpass of the Polk County Parkway and usually five to six motorcycles waiting. The spotters catch the speed and the motorcyclists chase them down. They are hard to see because of the shadows underneath the Polk County Parkway, so be cautious. It should also be noted that motorists have been very helpful in flashing their highbeams to warn others, so please do the same if you run through this trap.
