What+warnings+do+her+aunts+give+Yolanda+before+she+starts+on+her+journey?

Yolanda's aunts are horrified at the thought of Yolanda traveling by herself. They tell her that, being a woman, traveling alone is very dangerous and anything can happen, in particularly in the North. They try to dissuade her with boogeyman, haitan hougan, and communist kidnapper stories in hope of changing her mind.
