[Michlib-l] Outdoor book return question

We are moving to a temporary location while our facility is being renovated. Our existing book return fell apart during the move. What outdoor returns has michlib-l land found to be durable and able to withstand ice melting products, which I think helped send this one to an early demise? Thanks in advance for the advice. I would be happy to post a summary of responses. Eric Magness-Eubank Library Director Alpena County George N. Fletcher Public Library emeacl@alpenalibrary.org
