Hey Zen- they come through at 6:15PM. It's not dark yet. However, assuming they are riding single file or double file then speed would be the factor and yes, slow down is the correct answer. I still believe that the maneuver is an over reaction and is rarely used by state and local PD unless there is an immediate danger to public. This does not rise to such a level as it is a 5 mile strip with a fairly low presence of vehichles and pedestrians pretty much stick to the designated areas.
