How did the townspeople respond to the Northerners differently than they did the Southerners in "How It Feels to Be Colored Me"?

When reading this essay by Zora Neale Hurston, it is important to know her background.  Specifically, Hurston grew up in the town of Eatonville, Florida, the only all-black town in the United States, so "The only white people [Hurston] knew passed through the town going to or coming from Orlando."  These travelers were the only white people Hurston came into contact with when she was a child; they were a curiosity to her as well as the townspeople.  And the Northerners were treated as such by the town: "They were peered at cautiously from behind curtains by the timid. The more venturesome would come out on the porch to watch them go past and got just as much pleasure out of the tourists as the tourists got out of the village."  The Southerners, on the other hand, were known to the townspeople, so even though they were of a different ethnicity than the townspeople, they were known, and the people did not stop what they were doing to stare.  As well, Hurston notes, "The native whites rode dusty horses, the Northern tourists chugged down the sandy village road in automobiles," so the Northerners were easy to distinguish as they came through town.
