>>17631918san francisco is bad without a guide because of the homeless and drug dealers who reside on the streets of the tenderloin district, a large open air drug market. the police are especially abrasive, and aren't afraid to harass normal citizens. it's like going into the jungle without a direction. even my aunt, who lives in korea, is afraid of american black people, they have that bad of a reputation in this country.
also, why go from congested city, to congested city? don't you want to escape the "rat race"?
