We had some nasty wind on Mother's Day- nothing like the Southern states (Thank Goodness!!!), but enough wind to blow out the windows on our back porch. It wasn't just the glass that blew out, but the frame and all. The funny thing is that Michael and I were just talking about how nice it would be to enclose the back porch so tht we could use it more of the year. This may just be our opportunity to replace these cheap quality windows with something more decent and durable.
