Last summer as we were preparing to go to Alaska for three months we had lots of issues to deal with in our absence. One of which was the lawn mowing - and with that came the thought 'how do we protect our lower windows'. The thought of exterior shutters crossed through our minds, but we didn't have time. We ended up boarding them up so a stray stone wouldn't accidently break a window. Shutters would have been much prettier, but we weren't there to look at it.
