what about the other way... do you think it would do any harm to "index" them? that is what i'm thinking now. if it won't do any harm, then why not just let google index the whole lot? they probably won't bring in much traffic, but every little helps.
the pages all have proper content on them, they are not thin -- they are just out of date (the date of the event will still be shown on the page).
