I am seeking some help with a North Avenue crosswalk.  My daughter (7), niece (6) and nephew (9) all go to Flynn school.  The three cross North Ave. at the intersection of North Avenue and Barley Road.  It is a very busy intersection during mornings and afterschool.  There is usually, but not always, a crossing guard there.  There are many cars that exceed the speed limit in this section.  I have asked the police to make a presence there, but they are short staffed and it is also during a shift change.  Last year, when the crossing guard was holding up traffic a car went right through the crosswalk and almost hit my nephew with my daughter and niece following close behind.  This intersection is used by many people and there is no traffic light at it.  I am begging for help from you to put flashing crosswalk signs on the sides of the road to better alert drivers of kids walking across.
