On Saturday the 22nd Midlothian Science Festival are having a Science on the Wild Side day at Vogrie Park near Gorebridge. I'm going to be giving a talk at 12.30 aimed broadly at kids - it's free, but you can get tickets in advance. There's a lot going on - birds, mammals, archaeology, cycling, trees. Not cycling trees. Here's the site for more information: Science on the Wild Side.
