There are a few around the area but if I'm looking at
just Rock Island, it's probably the new
Jumers Casino and Hotel on the outskirts of town (aren't they all?) The economy hasn't really seemed to affect them.....yet. Perhaps it's because they're so new(opened in December) I haven't been there so far, I'm not big on gambling or casinos or people who frequent these places. I might stop by to check out the restaurants, though. That's about it.
