When Brigham Young first entered the Salt Lake Valley on July 24, 1847, he did so in the back of a fine, white carriage donated to the Mormon pioneer leader by a faithful follower, James Madison Flake. Young was ill and couldn't drive the rig himself, so Green Flake drove the carriage and was among those who actually heard Young say, "This is the right place."
And then, speaking to Green Flake, Young added, "Drive on!" Green Flake, at that time a black slave, was later given his freedom by Young.
