Heroes come in all kinds of packages.   In fact,  many heroes are not even recognized  –  least of all during their own lifetimes.   But with the recently observed Native American Day,  I thought I would share a few of mine  –  some that you may have heard of,  and other lesser-known aborigines of North America.   This is not by any stretch of the imagination,  a comprehensive list. It would be like trying to list all your favorite white people. The great Olympian Jim Thorpe
