Hi...I'm back !! I was in a car accident 2 weeks ago and then last week I had an ulcer on my cornea and couldn't see!! I am getting old and falling apart. Today is my first day back at work. It is clear what you were talking about. The pen is for outside but the only hutch that I found was not big enough for my "healthy" kids. I won't be going to Hawaii now because of the car accident ! But my boyfriend said he would take me.
