I am going to take a wild guess here and attribute some of his craziness/agression to the dot.com culture in Austin.
It was one of those austin dot.com buccaneers who shot all the buffalo out in colorado a while ago — buffalo that had come over onto his land through a broken face I believe.
And I know a couple of guys in that hothouse atmosphere. There’s a kind of ‘angry’ culture there, a kind of poseur macho thing, very leftist.
