What does Douglass see as a problem with the western people as to how they conduct the "Underground Railroad"?

Douglass sees the Underground Railroad as too public.... too exposed. He feels that this exposure makes it more difficult for others to escape. Douglass also notes that for all of their good intentions, the slaves "Western Friends" do not prepare those they save for life outside of the plantation. These slaves cannot find work and are unprepared for their freedom. Thus, freedom often becomes nothing more than another form of imprisonment.
