Most of us scramble the tale too, or at best know bits of the Longfellow poem.

Revere gave the sexton the lantern signals days before his ride- which was not to the Church. He warned colonists along the route that the British would take in Middlesex County.

He was captured and did warn some British troops that they would encounter danger if they approached Lexington. The troops freed Revere and others they had captured, and went back to warn their superiors.
Probably this was what Palin halfway remembered.

In some parts of the country, the story was not taught. In Santa Fe, we took New Mexico history, which was mostly about the Spanish-Mexican rule, and the Indians. We also had a course in world history.
When I entered university, I found that U.S. history was required, and I had to take it as a make-up course.

I think Palin would make a terrible president- she is ignorant of world cultures, and knows squat about economics.

But faulting her on Revere's Ride is picking on something most people would scramble.
