I think more than how 'werewolves' would act, it would be how the characters themselves act.  How much control do each one of them have? how much does each one actually care about getting caught? What is their morality level? What are they willing to do to keep themselves a secret from the outside world?  All of that comes from each character; rather than all werewolves as a whole...I think...I dunno.<br/><br/>Well, we could always do a cop out for the location, and have them be in some unnamed made up town/city. That way, whatever we want there: we can have.
