I haven't yet found a library with a frigate, though I'm sure there is one somewhere. Until I find it, take a look back at my posts for La Crosse, Wisconsin (river boat) and Escanaba, Michigan (sail boat). Then go to https://www.facebook.com/Durham.NH.Public.Library#!/Durham.NH.Public.Library. Scroll down to mid-July (the 19th, I think) and see their gundalow. Durham has a fantastic new library building that I hope to visit in December.
Any tips for other libraries with boats?
