"Dey darker den us! Woof!"
A meet and greet.
No it doesn't rub off!
Lewis and Clark, party time, very popular with the EM! And the Indians.
IIRC, L&C did not partake in the orgy.
In the autumn of 1804 when the Expedition reached what is now South Dakota and made contact with local Native American tribes, the Arikaras were astonished to see a black man. York, who was described as large and had curly hair, soon became the object of their attention. The Arikaras crowded around him touching his skin and hair and found it difficult to understand why his color did not come off.
Further reading... York was very popular with the Indian ladies, it's unlikely his descendants were slaves.
