From the excellent My Thoughts Be Bloody (about Edwin and John Wilkes Booth):

New Orleans' pleasures came at a price.    Many who flocked here annually never returned to their homes but remained in the city permanently, residents of the graveyard.

If people "flock here annually" they can't also "never return", can they?

I'd like to see something more here, such as "many of those who flocked..."
