A friend has night classes on York's campus, and was asking me about pepper spray. I warned her it's illegal, but I understand her concern - for as long as I can remember York has been known for rapes and assaults at night among their poorly lit alleys and walkways. Supposedly construction there right now is making it worse (I haven't been there in a while, sounds legit to me). I don't have any good advice for her. What does GTAM suggest?
