The some 30 entries on this granted very unscientific survey -- "Americans Try To Place European Countries On A Map " -- identified Spain (unlike many of the other European countries concerned) correctly, except for this entry (with no offense meant to Portugal from yours truly):
Could this unexpected American geographical expertise, despite the above erratum, be caused by the fact that, if one looks at a map, Spain is the "head" of Europe? (Italy, its foot, did also quite well in USA-all-the way recognition).
