I don't remember any of the kids running wild in the libraries visiting them as adults. We who didn't have a problem being quiet and going there to either read quietly or to bring books home, going there for the books, seem to be much more likely to actually visit as adults. Is there any evidence to suggest people who use libraries as playgrounds are more likely to use them as adults? Because if there isn't we are removing one of extremely few quiet places for no gain. I remember going to the library or staying after school to be able to read my Asimov and Douglas Adams, which would have been hard at home. If people who have quiet homes came there to let their children off to play I would be less likely to go there, just like I'm less likely to go there now when that is happening.
