Bet you will Max

I like CB's idea of shelter building ... maybe with a little prize for the best (not judged by any of the doting parents - not that any of us are biased of course!) If we picked a fairly central spot, or if they built them next to their mums and dads they could sleep in them on the Saturday night too ... be interesting if it rained but they'd love it!
Aswell as the shelter building, the only other thought I had was about a little group chat with them all about knife safety ... maybe Bernie or Andy (or several of the dads?) would be good for that but not sure how they'd make it fun and appealing! Any thoughts?
