Dear Barry,
Thanks a lot for your reply.

I just installed the 'firebug' debugger and I see the coordinates data you
discovered. I'll try to figure out if i can transform these coordinates (to
overlay them on a US map) or perhaps use them to place polygons. I'm
currently inspecting the code searching for data on the polygons.

Thanks again. Best regards,

Carlos
