Roughrider is 30 mph until about 30 ft from Windway going east where the speed limit drops to 20mph. The police wait in an alley on Windway. It also seemed odd that a car looking like a cab kept pointing at the police officer and waving at me as if they were working together as I turned on Windway. The streets Windway and Roughrider both have 4 lanes and are non residential and there are no schools anywhere for miles.
