Plains People and canoes is sort of like leiderhosen on a Spaniard. The Plains are a desert. There is not much out there to make a canoe from. If they used watercraft, it probably was made from skin stretched over a wicker frame. In any case, it was not central to their culture. I do not care for PC, but since our forefathers wiped out 98% of all these people and we are prospering quite well at their expense, the least we can do is not trivialize what little we know of their cultures. Get a copy of: The American Plains Indians - Osprey Men-At-Arms Series #163, to get a slight taste of their costumes in the 1800's.
