Many people walk their dogs around the perimeter of Overbrook School for the Blind. There are quite a few mostly with large dogs who do not pick up after them even though the $300 fine signs are posted. The fine is not enforced and calling them out has not helped. The students at the school are taught to navigate with their canes around the school. This is entirely unacceptable. 2 young men walk their pitbulls one white dog & one dark around 9-10 AM and 7-8 PM AND NEVER PICK UP AFTER THEM.
