Sounds like a wild rumor frankly .... Towns in Mexico burning bodies? I highly doubt it.
1) My cousin, she has the sniffles
2) I know this girl who is terribly sick
3) This girl, she has swine flu and comes from this crazy backwoods town
4) I hear in the backwoods town they are burning stacks of bodies in the street
and so it goes ....
I am sure not going down there to find out.
