Another thought...
Considering the ethnicity of those crossing the border -- Haitians, i.e. blacks -- also consider what time of year it is.
The middle of summer.
Even up around Rouse's Point, New York (where this is happening) this is a balmy time of year.
I wonder how those Haitians are gonna feel by the time January rolls around up there in Montreal...? Think they'll start having second thoughts...?
