Where is the library in Stormville?

Unfortunately, there are no libraries in Stormville. The closest one (and it's a pretty solid one as libraries go) is the East Fishkill Community Library in Hopewell Junction. You'd probably be looking at a drive of less than 10 minutes to get there.

To the northeast of town, there's also the Beekman Library, which might be a little farther depending on where in Stormville you are, but it shouldn't be too much more distant than the one in Hopewell.
