I have seen the Alamo and the quote from Davy Crocket "You may all go to hell. I shall go to Texas".
The Alamo is a tiny building and it was part of the mission system here in Texas. In San Antonio there are several within a few miles of each other. We have hispanic cowboys now and supposedly the difference between a real cowboy and a fake is how shiny new his boots/truck is. There are still cowboys and Indians and ofttimes(in Texas, anyway) they are the same guys.
Being a cowboy is a JOB and there are still cows, still cowboys all over the world. The basic conflict in the 1800's was won by whites as they control most of the land now. The conflict was about land then (and where I am from, fishing rights, now) but it usually IS about land-everywhere in the world, isn't it? Just different native populations-results vary!
