On the first morning of February, Boston Police Commissioner William Evans and his officers joined youngsters from the Ellis School on a snowy walk in the Roxbury neighborhood on Walk to School Day. The students wore yellow vests and carried signs that said “Heads Up, Phones Down” and “Stay Alert-See and Be Seen” to raise the awareness of drivers and pedestrians alike on the topic of street safety. Even with the cold temps and a dusting of snow on the ground, these smiles could be seen for miles!
