Thanks for getting in touch. I've a website and a blog called I'm a teacher get me OUTSIDE here!. Any questions, please ask. I see I'd also called you Donald - take that as a compliment as it's a good Scottish name! (And sorry)
This is a bit of a belated welcome from the other side of the world. I hope your nature play work is going well and please do get in touch if you ever want UK info where the play sector is leading the way nationally in terms of approaches to risk and getting children outside.
