That's true of the Central American stuff, provided there is a footprint in the States. Here I can receive Sky Mexico's few ITC channels more or less reliably with a 1.2 meter dish.
How about the west coast? Elevation-wise, Vancouver can see to Superbird B2 at 162E (that's 198W for North Americans). Not sure there's much of a footprint from those satellites on us though. And the southern guys must have lots of good South American stuff.
