The Lewis and Clark enactors took the official vote at Station Camp.
"That evening, the commanding officers polled the entire group to see where they wanted to spend the winter. The historic vote included a vote from the lone female in the group, Sacagawea, and William Clark’s slave, York. This is believed to be the first time on American soil that women and blacks were given a vote."
And with that historic vote... they journeyed across the Columbia River to winter on the south side. (Many of these re-enactors are relatives of the actual people they are portraying.)
