My daughter and family are visiting Knebworth today and will no doubt visit the Dinosaur Park with their young son Alfie. I wonder if there is any way I could give them a surprise gift - lunch in a cafe etc? We used to live in Stevenage in the 80s and went to the firt concerts that were put on. I have embarrassed our daughter by posting pictures on Facebook of her jumping about in a whale that you used to have in your grounds!!
