Something about its flow just puts me off. Some names or words just kind of have an unpleasant feeling when I say them. Carmichael is another that I can think of off the top of my head. It's hard to describe it--cheesy or smarmy is probably what I'm going for. Laramie totally fits that bill.
The fictional cigarette brand and the fort don't bother me, which are the first things I think of. But the sound of it does.
