Kevin,
Here's a few Western History type sights I've been visting lately (I've been writing a Western and they've given me some good research material)

(This sight's a tribute to Lonesome Dove, but it has a "today in old west history" page that's interesting)

Jim Jakes Old West

Didn't know if you've already had these or not, if not I hope they help.
