Here is why I am asking.
I notice the crossing guards @ Vintage hills + Mohr and the guard @ valley/koln st. are on duty for a longer period of time.
The guard who is situated @ Santa Rita and black ave, is posted for a VERY short period of time. I would say less than 30 minutes total in the am and again 30 minutes in PM (30 minutes is generous) + The guard only crosses 1/2 the street (direction downtown) but not the side going toward valley.
The intersection of santa rita and Black are dangerous. Cars seem to go over the speed limit and when making turns they pay attention to the vehicle traffic but not so much pedestrians.
I doubt a good reason exists for the limited crossing guard activity at this intersection, but if anyone knows, please inform.
