Hey wow thanks for the responce. I will upload photos just as soon as i can get them off my camera. mocropot, might not help you but i put a beam across the middle of the raised bed then cover with 2 sheets of glass from a old window like a ' A Frame ' with the sides open. It has been my experience that its the wet not the cold that gets them.... but its not that cold in seattle. You could allways build a small frame with plywood sides and then layer 6 ml clear plastic sheeting over it. Also dont forget some of the old tricks, ive never tryed myself but...
