Last time I was in California I brought a visit to the Universal Studio's, there was an native American section, there was a big shop which sold Sioux souvenirs, there worked Sioux guys there (maybe mixed and not 100% Indian) I was looking to the pictures of their leaders and their arts. It was a hot summer and I was everyday at the beach so I was very brownish, I also had long hair. A guy told me where I am from, I told him from Senegal, he said you don't look African at all, I said I am originally from Iran. Then that guy said Great God, I thought you were native American too, an older guy told me that he also believed that the Sioux have caucasian influences, so they have a big nose and bigger eyes, not a little nose and narrow eyes as the Mongolians, but very interesting was the motifs on their carpets, which that old wise man said also they look very Iranian, I saw a book with all of Sioux motifs in it, also their religion resembles ours, their God is Wakan T
