Thanks. Might be the annotation coordinate list then. The MapKit annotation list entries use CLLocationCoordinate2D of CLLocationDegrees for long and lat.
Xcode straight out SIGABRTs when trying to convert the mapView.annotations. Looks like I'll have to convert those location Degrees to NSStrings and try again. Thanks for showing me those notes from the Serialization Class Reference. The line of code wasn't even returning an error so it was a little hard to figure out what was going on.
