Too bad I can't be of any help.
I used to live in Florence, myself (Up until about a month and a half ago).
Only of few people from that area (The coast, that is) ever make it here. I know another persom from Florence has made it here, but thats about it.
As for a manga club, or something, I know Newport has a video game store. Usually, alot of people are into the same kinds of things, so I would recommend seeing if anybody there is interested, and wants to help.
I know they have a video game store because I worked at the Florence branch for a little while before having to move. The guys down in Newport are rather nice, so I am sure if ya told them the situation, they'd even try and help out.
Other than that, I really don't have much advice.
Oh, get used to the rainy weather, and sand getting EVERYWHERE.
Best of luck.
