Well, and you should decide what kind of reenacting you want to do. The east coast does tend to have a lot more events and they do tend to be more accurate in terms of dress. The western events are a bit more of a mixed bag in terms of dress, with the full range of authentic to fantasy garb, but there's a much greater chance of the piratical events involving an actual ship - that you have an outside chance of being on. So it's a matter of what floats your boat.
Oregon has, in recent years, become the venue for a number of piratical events, both in the northern and southern parts of the state, so it is worth another look if you have lived there before and liked the experience.
