geez, a daytime bart trail attack

my dilemma right now, and more as we head into shorter days, is that I have to strategize my mile trek from del norte bart to my home on schmidt lane for safety.  my thoughts-
is the plaza a safer walk? is that stretch of san pablo a safer walk?
should i get pepper spray and walk with it in my hand?
should i really wait for a bus to get me to my house? or a cab?
maybe i can request to change my schedule at work so i don't have to walk after dark.
should i buy a skateboard or razor so i can zip through my mile walk?  i have a bike that i ride at times, and that is a no brainer that it is safer, but i am not always able to ride it as part of my commute.
No doubt, i have always done my part to be as unattractive to predators, and im sad to say that i see many sitting ducks everyday that i walk the path.
well, ill close on a positive note.  I moved back to this lil town because i know that it's residents care and actively take part in what is happening on their streets.
