Every day at different times you can spot an Arlington County Police cruiser, marked or unmarked, parked on either side of Route 50, between Carlin Springs Drive and George Mason Drive, most of the time at the light at the intersection of N. Henderson Drive and Rt 50 as people accelerating up the hill find it undesirable to stop for a yellow light at this intersection. Additionally, as you go through the light in either direction you begin to head downhill, able to pick up a lot of speed.
