I think the family members of most Crockett High School students are pretty good drivers. However, with that said, there are definitely exceptions, and to those people, I offer this free advice:
Manchaca Road is a really bad place to stop to let off your kid. This is especially true when the school zone is not in operation. You may have noticed that there are convenient parking lots located directly off Manchaca into which you may turn. Please avail yourself of the opportunity to do so.
Your fellow drivers would appreciate it.
