Hmmm.... you see lots of cops on Kingsway where all the hoes are, and you ask "is it safe to cruise". To be a keen observer is worthless if your mind refuses to see.
Short answer - it is never safe to cruise for ho's. And with low selection and high likelihood or sub-par experience, stick to MP or independents. The streets ain't the cruiser's hey-days of the mid 90's.
