This is taken from the feedback provided by the Nottingham Galleries of Justice who run the Caves complex:
"We were approached by Rob Hann and Howard Barton to develop a tour at our visitor attraction City of Caves to be based on their book “The GrumbleGroar”. We thought this would be both exciting and challenging but more importantly show the caves in a different way to our family audience.
We ran these tours throughout the school summer holidays, dividing the day with GrumbleGroar tours in the morning and our regular tours in the afternoon. 86% of the visitors surveyed rated the tour 5 or 6 out of 6, giving it an excellent satisfaction rating amongst the target audience.
Whilst we had many challenges along the way we would fully consider a similar collaboration in the future."
The GrumbleGroar also appeared over Halloween at David LLoyd West Bridgford where it had built its 'Lair' for a whole week before it disappeared once again to the centre of the earth. Here is what the Kids Crew at David Lloyd had to say:
"It was an absolute pleasure to have you attend the Club with the outstanding GrumbleGroar for the whole of Half Term. The props were excellent, the activities met our wishes for premium product for the Kids camp, and the reading (that you a real author did) and video have stimulated a lot of interest.
We love your work and hope that we can progress more projects with you in the future."

I hope more children will benefit from exposure to the GrumbleGroar's exclusive talents in 2017 and the book will inspire children and parents alike to discover what really happens, deep deep down beneath our feet.
